Privacy’s still beating heart and the social media challenge

The changing habits of younger web surfers are challenging the assumptions underlying social media services.

“I’m not a very public person,” twenty-two year old Walter Woodman tells the New Yorker in How A Relationship Dies on Facebook.

One of the assumptions of the social media industry is that digital natives, those born after 1990, have little if any expectations of privacy. The New Yorker story challenges that idea.

Much of the New Yorker’s background is taken from the Pew Centre’s May 2013 report Teens, Social Media and Privacy which interviewed 802 US teens and their parents to identify young adults’ attitudes towards privacy.

As the Pew Centre’s Mary Madden wrote in a follow up post to that report, US teenagers aren’t about to about to abandon Facebook yet but they are concerned about privacy and the work involved in managing an online persona.

While some of our teen focus group participants reported positive feelings about their use of Facebook, many spoke negatively about an increasing adult presence, the high stakes of managing self-presentation on the site, the burden of negative social interactions (“drama”), or feeling overwhelmed by friends who share too much.

This suggests a far more mature, and complex, understanding of privacy by teenagers than many of the social media boosters assumed when declaring that privacy is irrelevant in the Facebook era.

Like their parents, teenagers and young adults know there are consequences for sharing too much online which challenges the social media platforms that have built their businesses around users spilling everything about themselves into the big data pot.

It turns out digital natives are just as conscious of the risks as their parents, although how they handle it may manifest in different ways, and the assumptions of many social media businesses aren’t quite as robust as they appeared not so long ago.

Kinkabool – the highrise past and future

A visit to the Gold Coast’s oldest high rise raises some questions about sustainability.

Today high rise buildings are the norm on Queensland’s Gold Coast, but just over fifty years ago in Surfers Paradise, nine storey Kinkabool was the first of the breed to be built. Its condition today is a warning on how skyscrapers can turn into expensive liabilities for owners.

ABC Open has an interview with one of the workers on the building and in the accompanying video Bob Nancarrow shows just how Kinkabool dominated the then sleepy seaside resort of Surfers Paradise in 1960.

A visit to Kinkabool today reveals a building struggling in the face of poor maintenance and an undercapitalised ownership. Luckily for the owners’ corporation, the Queensland government pitched in to repair the roof but much of the rest of the complex is showing its age.

The rabbit warren lobby with its orange tiles indicate some of the building was upgraded in the 1970s but apart from a lick of paint, it hasn’t seen much love since.

The lift is are where the building’s age and owners’ lack of investment really shows. An old, slow elevator that hasn’t been upgraded since the first residents moved in clunks its way up the building. Even Hong Kong’s Chunking Mansions – the world’s best example of a dysfunctional high rise – gets its lifts upgraded sometime.

Inside the lift, it’s a depressing scene and one wonders if the antiquated equipment would meet today’s building standards. Even if it does meet the regulations, the dispiriting ride on its own would knock a big chunk off the asking prices for buyers or renters.

Stepping out of the lift, the view in the stairwell isn’t much better. The lack of maintenance or investment begins to show in old fittings, damaged glass and hints of painted over graffiti.

While standing on the ninth floor, music from unit 1B drifts through the building – it’s lucky the occupant has a taste in cheesy 1970s music as some thumping headbanger music could to serious damage to the building along with the residents’ sanity.

One wonders just how noisy the building would be with a party happening or a young, crying baby although it seems families aren’t really interested in these apartments or the central Surfers Paradise location.

Though a very undistinguished building, it does have one touching little architectural feature in the different tile patterns on each floor, although probably not enough to redeem it in the eyes of most people.

Probably the saddest thing about Kinkabool is how a building that once dwarfed everything in the region is now overshadowed by its much bigger neighbours.

Across the road, and blocking out most of Kinkabool’s sunlight, is the 1980s Paradise Centre.

Time isn’t proving any kinder towards the Paradise Centre with the lack of maintenance beginning to show on the thirty-year old complex as this vent across the street from Kinkabool illustrates.

Generally, if the landlord or owners’ corporation is too stingy to afford a coat of paint, then you can be sure there are more nasty surprises

Both the Paradise Centre’s and Kinkabool’s declines illustrate a much more fundamental problem in an economy driven by property speculation and taxation allowances — there isn’t a lot of money to go around for maintaining older buildings.

While Kinkabool’s residents can get by with a clapped out lift, inhabitants of larger and more modern complexes like the Paradise Centre will find the costs of running and maintaining their buildings an increasingly difficult burden.

It could just turn out that Kinkabool, should it escape the wrecker’s ball, may well turn out the more desirable dwelling than its bigger, more modern neighbours.

For the meantime though, Kinkabool marks the beginning of a far more sophisticated era in Australian and Gold Coast history. Whether that era became too sophisticated for itself remains to be seen.

Evolving cities and Silicon Valley’s private buses

What do Silicon Valley’s corporate buses tell us about the way our cities are evolving?

One of the phenomenon of Silicon Valley’s development has been the rise of the ‘Google Buses’ – the private services run by the big tech companies to shuttle their workers between home and their workplaces.

The Bay Area’s private bus shuttles are a real time illustration of how regions evolve around industries and economies and how cities and communities are in many ways dynamic, living creatures themselves.

An effect of the Google Buses is that San Fransisco is experiencing a ‘reverse sprawl’ notes Eric Rodenbeck in his Wired Magazine story Mapping Silicon Valley’s Gentrification Problem Through Corporate Shuttle Routes

It’s about more than gentrification as we’ve experienced it thus far: It’s about an entirely reconfigured relationship between density and sprawl, and it’s going to need new maps to help us navigate this landscape.

Driving those buses is instructive as well and Buzzfeed has an interview with an anonymous driver employed by one of the bus companies. The driver’s tale shows the scale of the phenomenon.

This bus holds 52 people and that is 52 cars that are not on the road in one trip, and we have 70 routes in our system. That’s thousands of cars everyday.

Driving cars is fundamental to the American – and Australian – lifestyle. The modern American city developed around the motor car and that mobility is the defining feature of the Twentieth Century.

So maybe the Google Buses are an early part of the redefinition of our cities to meet the the needs of the 21st Century and cars are not the driving factor.

In this vein, Jarrett’s Walker’s Human Transit blog teases out some of the issues behind these developments.

Finally, this joke is on the lords of Silicon Valley itself. The industry that liberated millions from the tyranny of distance remains mired in its own desperately car-dependent world of corporate campuses, where being too-far-to-walk from a Caltrain station — and from anything else of interest — is almost a point of pride. But meanwhile, top employees are rejecting the lifestyle that that location implies.

While I don’t agree with Jarrett’s proposition that the geeks riding these buses want to mingle with strangers given the locations they live – I’d argue they’re attracted to those locations because their peers live there and downtown amenity to good restaurants and bars – he raises a very good point about the mismatch between where the workers and the jobs are.

Jarrett’s point touches on land use zoning and its effects on the evolution of cities. An excellent piece by Alexis Madrigal in The Atlantic tracked Silicon Valley’s iconic techonolgy sites, most of which have been demolished due to the pollution partly caused by zoning requirements for underground tanks.

The issue of zoning is also raised by Rodenbeck who points out that zoning issues with carparks are what has made employee buses more attractive to the giant tech employees.

Zoning different land uses makes sense on one level as no-one wants to live next door to a tannery, heavy metal waste dump or quarry, but there’s a risk with fixed ideas that our cities will become less responsive to economic developments, particularly in an era when people don’t want to, or can’t, dive across town to get to their jobs.

What Silicon Valley’s corporate buses really show is that our cities are evolving around the needs of today, not yesterday. It’s something governments, businesses, investors and communities should keep in mind.

Making way for Gen Y in the executive suite

A challenge for organisations is opening the career path for Gen Y managers as baby boomers hang around the executive suite.

One of the great challenges in today’s workplace is how organisations will manage Generation Y entering the boardroom.

Lazy, unfocused and high maintenance are some of the descriptions used by boomers when talking about younger workers, but how much truth is there really in that and how do organisations plan for this generation to take leadership positions?

As part of the recent Sydney EMC Forum, I had a chance to discuss the challenges of managing Gen Ys with social researcher Micheal McQueen and EMC Australia Managing Director Alister Dias.

Like many tech companies, EMC has a younger workforce with around 25% of staff being GenY and Diaz sees global thinking and a fresh, bright approach as some of the advantages younger people bring to the workplace.

“We want to see this grow,” says Diaz. “There’s two reasons for this; one is that energy level, quick learning and adaption to the new world but the other is the shortage of general talent in the market.”

That shortage is an early part of the global race for talent, with Diaz seeing the priority for EMC and other tech companies to develop home grown skills rather than importing skilled workers.

Offering a career

For Diaz’s, one of the great challenges in this race for talent is retaining skilled and motivated Gen Y and Gen X through offering more diverse career options.

Career progression is one of the big problems facing both GenY and X workers as, in McQueen’s view, the baby boomers have no intention of going anywhere as many define themselves by their work so they don’t plan to retire.

“For Baby Boomers their work ethic is their identity,” says McQueen. “Stepping back from a leadership position, or any position in general is a big deal.”

Not working huge hours which is a key difference between baby boomers and their GenY kids and grandkids who don’t wear long hours as a badge of honour.

Language barriers

An area that concerns McQueen is a lack of vocabulary as text and social media messaging has eroded the teenagers vocabulary with average 14 year old today only knowing 10,000 words as opposed to 25,000 in 1950.

“It started off as text speak and it’s gone beyond that now,” says McQueen. “If you have a Gen Y person operating with older workers there’s often a disconnect there.”

The effects of electronic gaming and communications also has created a climate where today’s teenagers have less empathy than those of twenty years ago — McQueen cites a University of Michigan study — this has consequences in fields as disparate as sales, technical support and nursing.

Organisations are going to have to learn to deal with these differences. “In our own organisation we talk about the need to adapt to Gen Y,” says EMC’s Diaz. “Personally I think we have to meet them half-way.”

“We’ve found it difficult to get talent. You really have to do your homework on it.”

Part of EMC’s problem in finding skilled Gen Y workers has been the collapse in university IT course enrolments along with the broader turning away from STEM — Science, Technology, Engineering and Mathmetics — related degrees.

Diaz is quite positive on this and sees the pendulum swinging back towards more technical degrees and diplomas with more younger people taking on STEM subjects. At present though enrolment statistics aren’t bearing this out.

Finding those skilled workers is going to be one of the great challenges for business in planning for the rise of GenY workers, one of the greater tasks though might be getting the baby boomers out of the corner office.

Never going to let you go – the failing businesses clinging desperately to baby boomers

As younger people turn away from old business models, those comfortable with the status quo cling desperately to their established but shrinking markets

Probably the driving factor of the consumerist society’s development was the baby boomers’ growing up.

Through the last fifty years everything from Coca-Cola to baby products and hair loss treatments has been aimed at the cohort born between 1945 and 65.

For many businesses and marketers this group has been so profitable it’s been hard to let them go.

The US motor industry is a good example of this with Bloomberg reporting the over 55 age groups are dominating domestic car sales as younger folk turn away from car ownership.

A similar thing is happening in Australia as TV executives decide that competing with the internet for millennials is too difficult so sticking with the over 50s market is safer.

“We’d go out of business if we stayed with our traditional demographic of 16-39.” Channel Ten CEO Hamish McLennan told the Mumbrella360 conference in Sydney earlier this year.

The problem for both the US motor manufacturers and Australian TV stations is the trends are against them.

For TV stations trying to compete against the internet, the older age groups are following their kids across to the web at the same time that they are beginning to save for retirement.

That need to save is also working against the car dealers, while many boomers fawn over new cars a large number simply aren’t going to be able to afford these indulgences. It’s not a good prospect for the motor industry.

In the meantime, younger people are turning away from the motor car, Bloomberg quotes University of Michigan Transportation Research Institute s researcher Michael Sivak who penned a report on generational shifts in the US motor industry.

“I have a son who lives in San Francisco; when I get a new car and I tell him what I got, he couldn’t care less,” Sivak said. “To him, it’s a means of getting from A to B. He goes into great lengths about taking a BART or bus, even though it takes him an hour longer. He does have a car, but uses it very rarely.”

The movement away from the motor car indicates something much more profound about western society — if the baby boomer represented the age of consumerism, the entire Twentieth Century was defined by the automobile.

For politicians and town planners wedded to a 1950s view of economic development, it may be they are making terrible and expensive mistakes in pushing freeway and other road projects.

While aging baby boomers purr over their expensive cars, the forces of history may be passing them by. Those businesses pandering to those older groups might just want to consider whether they want to be left behind as the economy, and the kids, move on.

It’s comfortable to cling onto what has worked for the last fifty years, but sometimes the lowest risk lies in letting go.

Downward trends and demographics mark the end of consumerism

The age of ever expanding consumer spending is over, we have to start thinking of different ways

One of the features of the late Twentieth Century economy was how consumer spending came to dominate the economy – as manufacturing moved offshore, mines closed down and agriculture became largely automated, many developed nations’ growth came from retail spending.

Today’s release of retail spending figures by the Australian Bureau of statistics shows how that economic model too has come to an end. A post on the Macrobusiness blog illustrates the steady, structural decline of retail spending in Australia.

Since 2000, the rate of growth has been declining, only low interest rate policies over the last two years has kept retail sales at a steady level.

Those businesses whose business models are built on the assumption of high growth rates have a big problem – its no coincidence it’s the department and clothing stores are among the loudest complainers about taxes, labour costs and rents as they see their sales and profits shrinking.

Basically the Twentieth Century era of consumption has come to an end as households have maxed out their credit cards. Now that many of those households are now older, they simply don’t need to spend as much anyway.

With the demographic, economic and cultural changes now happening in society it’s a bad time to be planning on massive expansions in household spending and debt as we say in most western countries from the 1960s onward.

It’s time to think different, and be a lot smarter about getting consumers to buy your products. The era of the 72-month interest free deal is over.

Gen Y and the need for building new businesses

As baby boomers struggle to maintain their living standards, the burden will fall on younger generations to build future businesses.

The retirement of the baby boomers has been an demographic inevitability, but it’s interesting how policy makers and the population in general have ignored the ramifications of this despite the first boomers now aged beyond 65.

One of the consequences of this is we may see an entire generation being forced to become self employed entrepreneurs.

Illustrating this point are two stories from the US over the last few days; John Mauldin’s dissection of where US jobs are going and Zero Hedge’s 35 facts that should scare American baby boomers.

The 35 facts really boil down to one thing, that an affluent, middle class retirement at 65 when average life expectancy is 78 is an illusion for most people – neither their bank accounts or the state treasury can support that sort of spending.

Which is the point of John Mauldin’s column, that over 50s are taking most of the available US jobs as they can’t afford to retire.

For those over 50 who’ve fallen out of the workforce due to unemployment or illness, getting back into the workforce is proving to be tough and for many of those folk their later years are going to be a struggle.

Equally, as Mauldin points out, the younger generation is being locked out of the jobs being hogged by the over 50s.

Another aspect to that is those employed Gen-X’s and Y’s hoping to get a crack at a seniors manager’s job or their name on the partner’s list are going to find a longer wait as the boomers hold on for as long as they can.

Those young ‘uns need those high salary jobs too, a Westpac report on US student debt posits that crippling education costs are making it harder for graduates to participate in the workforce and affects their spending power when they do find a job.

What’s clear is existing government, corporate and social structures are beginning to struggle with the realities of the changing workforce and its demographic composition.

On a personal level, those Gen Xs, Ys and boomers who are locked out of the workforce have to find a new way to participate in the economy. It’s probably those locked out of today’s workplaces who will build the businesses of the future.

The myth of the baby boomer

Are we making a mistake when we talk about the demographics of baby boomers?

Yesterday I was at the release of Deloitte’s State of Media Democracy report when something that’s been bugging me for a while became clear – have we got our definitions of baby boomers wrong?

In the report’s demographic breakup was the usual breakdown of age groups with the interesting twist of separating ‘leading Millennials’ and ‘trailing Millennials’.

Such separation makes sense, how a sixteen year old uses the media is very different from that of a 26 year old, however there’s a good argument breaking up the baby boomer group the same way.

While there’s no denying the post World War II baby boom in most Western countries that lasted roughly from 1945 to 1965, lumping the entire group into one demographic bubble with the same economic characteristics seems mistaken.

If nothing else, the baby boomers should be broken into two groups – those born before 1955 and those afterwards.

Those born between 1945 and 55 had the benefit of being born into the a world rebuilding from the second world war and the massive improvement in living standards that accompanied the reconstruction.

For those born after 1955 their work experience was very different; the 1973 oil shock marked the end of the post war economic certainties and also saw the beginning of increased casualisation of the workforce through the deregulations that accelerated under the Reagan, Thatcher and other Western governments in the 1970s and 80s.

In many ways, the 1955-65 cohort of baby boomers have more in common with the generation who followed them – the Generation Xers, the term coined by the author Douglas Coupland who was born in 1961.

Equally, the earlier half of the baby boomers have much more in common with those born between 1935 and 45, the ‘war babies’ were too young to fight in World War II and they benefited greatest of all from the post war economic boom.

So perhaps we should be talking of the ‘Lucky Generation’ – those born between 1935 and 55 – and redefining ‘Generation X’ as those born 1955 and 80.

While it’s easy to say “who cares”, there’s an important aspect to this. Much of our discussion about the aging population revolves around the boomers retiring and the load this puts on the community.

Not to mention the foibles, beliefs and voting patterns of the boomers which again differ markedly between the ‘early boomers’ and ‘late boomers’.

If we accept that the tipping point wasn’t in 2010 when the first baby boomers reached retirement, but in 2000 when the ‘lucky generation’ started retiring then this discussion about how we service a growing – and demanding – group of retirees becomes even more pressing.

As in many things, life is a lot more complex than the lazy assumptions of demographers and economists would have us believe.

The myth that the baby boomers are one big fat group with equal demands, needs and assets is something may turn out to fool many of our business and political leaders.

Silicon Valley’s network effect

How do cities emulate industrial centres like Silicon Valley and San Francisco

Philip Rosedale, the founder of Second Life and various others startups has an interesting take on why San Francisco and Silicon Valley are the centres of the tech startup world.

He puts the region’s success down to the network effect where like minded groups share knowledge and encourage each other.

If you want to create a vibrant start-up ecosystem somewhere else that is competitive with San Francisco and Silicon Valley (and this is starting to happen right now in places such as Boulder and Austin), you want to do two things: You want to pack the people working together into as dense an area as possible, with public areas and co-working venues where they will see each other constantly, even when they aren’t working in the same company. And then you want to encourage them to let down their guard and be as open as possible about what they are doing.

Of course the network effect doesn’t just apply to the Silicon Valley tech startup model, it’s just as true for China’s manufacturing hubs, South Korean shipbuilding or historical centres like Detroit’s motor industry and the English Midlands during the industrial revolution.

We shouldn’t forget that fifty years ago governments sought to to emulate Detroit’s success and a century ago cities strived to be like Birmingham.

That’s something we should keep in mind when looking at ways to emulate Silicon Valley – in trying to copy today’s successes, we may be mimicking a model that has already peaked while overlooking our own unique advantages and the opportunities in new industries.

For cities striving to become world centres of industry, it might be best to first figure out what they do well and then find a way of attracting the smartest people in that field to move there.

Then again, it may just be that most industrial hubs are accidents of history and the best we can do is try to attract smart people to our communities.

A business lesson from the Catholic Church

The election of Pope Francis shows why the Catholic church is such a successful business. Many of us could learn from them.

The Catholic church may be a two thousand year old institution with medieval beliefs and beset with scandal, but the clerics know how to handle business succession well.

Pope Benedict’s resignation was not only unexpected but also almost unprecedented with it being six hundred years since a pontiff quit before dying on the job.

In many organisations such an unexpected and rare event – dare one use the ‘black swan’ line – would create havoc, or at least paralysis. Instead the clerics handled the process smoothly.

This contrasts with the succession planning in many companies. In larger business even when the CEOs handover is planned, there’s a period of write downs and blood letting as the new leader stamps their authority.

Sometimes it gets very ugly indeed, particularly if the former CEO has been kicked upstairs onto the board.

In smaller businesses, there’s no succession planning at all. Many businesses die when the owner retires if there’s no buyer for the operation.

That shortage of buyers is a major problem for smaller business owners. Many baby boomers have planned their retirements around getting a good sale price for their businesses.

If they can’t get the sale price, the boomer small business owners work until they drop.

Which is what popes usually do.

It’s often said the Catholic Church is the biggest corporation on the planet. Given how smoothly their bureaucracy deals with succession planning, that’s not surprising.

Australia welcomes the multi generational mortgage

Australia starts to repeat Japan’s experience with multi generational mortgages. With a twist that might be more debilitating than the Japanese lost decades.

At the height of the Japanese property boom in the 1980s, the hundred year mortgage came into being.

Pushing payments onto children and grand-children was the only way home prices could continue to rise once they hit levels which the average Japanese worker could ever afford with a more traditional twenty or thirty year mortgage.

Twenty five years later Australia finds itself in a similar position as parents guarantee their childrens’ mortgages.

Repeating the Japanese mistake

While the Japanese looked to sticking their mortgages onto their kids and grandkids, Down Under the kids are fighting back and getting mum and dad to underwrite their unaffordable loans.

This weekend’s Sydney Morning Herald features in its property section the story of how Sharon and Graeme Bruce guaranteed their son’s and his fiance’s mortgage in Sydney’s inner suburbs.

While the story isn’t clear on the size of the deposit (which isn’t surprising given the SMH’s shoddy editing), it appears the Bruces’ have guaranteed around $300,000 so his son and future daughter-in-law can grab a five bedroom, 1.45 million dollar mansion.

One wonders what great businesses Matt and Hannah could build if mum and dad were prepared to stump up a similar amount to invest in a start up?

Australia’s property obsession

Sadly we’ll never know – in Australia, the smart money gets a job, pays off a mortgage and accumulates wealth through investment properties. What cows are to African tribesmen, negatively geared units are to the Australian middle class.

The hundred year strategy hasn’t worked too well for Japan, with a declining population those mortgages entered into a boom level 1980s values now don’t look so attractive and are one large reason for the nation’s lost decades.

In Australia, things aren’t likely to work so well either. The Baby Boomers and Lucky Generationals – those born from 1930 to 1945 – guaranteeing their kids’ and grandkids’ mortgages are relying on ever increasing property prices.

This is understandable given that few of them have any experience of long term stagnation, let alone decline, of property values but it leaves them incredibly exposed should the Aussie housing market slump.

Can an Aussie property decline happen?

Many Australians, particularly those with vested interests, maintain such a decline can’t happen but the prospects aren’t good as the SMH story shows;

The couple had attempted to buy a small terrace in Newtown but kept getting pipped at the post by other young professional couples. At a higher price point they had no competition.

Despite his parents’ generosity he said he would still need to rent out a few of the rooms to help pay for the mortgage.

So Matt can’t afford the mortgage. That’s not good starting point and one that could cost his parents dearly, which they don’t seem to care about much.

”Obviously my dad guaranteeing the loan was the only way we were going to purchase this,” Mr Bruce said. ”You need to have a 20 per cent deposit otherwise the banks want you to pay insurance … it’s a bit of a rort really.”

It’s fair to call mortgage insurance a rort – as it certainly is – but its purpose is to protect the banks should a mortgagee default and the financiers find themselves out of pocket.

With Matt’s parents getting him out of paying that insurance his bank has much better default protection, equity in his parents’ property.

Guaranteeing risk and misery

I’m not privy to the finances of Sharon and Bruce, but most of their contemporaries can ill afford to lose several hundred thousand dollars in home equity in their later years.

That is where Australia’s multi-generational mortgages could turn very nasty, very quickly as older Australians find themselves having to deliver on the guarantees they gave on behalf of their over committed offspring.

In Japan, it’s taken a long time for the population to realise their national wealth has been squandered on twenty years of propping up unsustainable property prices and economic policies.

One wonders how long it will takes Australians to realise the same has happened to them and what the political reaction will be.

Facebook’s struggle to stay relevant

Are Facebook’s advertising policies alienating users and leaving advertisers unimpressed?

Are we getting sick of Facebook? Tech magazine CNet stirred up the interwebs on the weekend with the claim that Teenagers are Tiring of Facebook a meme was pushed by the New York Times’ Nick Bilton dissecting his experience with the service.

It’s not just teenagers moving away from social media sites though, many adults are getting sick of intrusive adverts and promoted posts getting in the way of the news about family and friends.

As an example, here are the ads taken off the page of one fifty year old woman’s feed.

“I find these offensive” she says, “I’ve been posting my results from a fitness program and now my Facebook page is plastered with ugly weight loss advertisements.”

Clearly the targeted advertisements are working too well and clumsy marketers are destroying the user experience with ugly and offensive ads.

Not that those ads are working as Nick Bilton found when he decided to promote a post to his 400,000 followers.

From the four columns I shared in January, I have averaged 30 likes and two shares a post. Some attract as few as 11 likes. Photo interaction has plummeted, too. A year ago, pictures would receive thousands of likes each; now, they average 100. I checked the feeds of other tech bloggers, including MG Siegler of TechCrunch and reporters from The New York Times, and the same drop has occurred.

When he decided to advertise, his engagement went up by ten times. Leading Nick to conclude that Facebook were suppressing his unpaid posts while pushing the one’s he pays to promote.

Even for advertisers, a few hundred likes doesn’t translate into much of a return.

That suppression of useful posts is one of the reasons teenagers are moving, one 17 year old I asked about why he’s moved from Facebook said the ads cluttered up his feed.

Which leads us to the reason why people use Facebook – they use it to talk to friends and relatives; not to watch ads.

It took commercial radio and television a decade to figure out the right mix of advertisements and contents, a balance that is still tested today. Social media sites are going to have to get that mix right soon.

Facebook has the most at stake and their time is running out.
