Is pigging out on Facebook and Twitter just a fad or can it be useful?

Is it better to be useful or make money? In reallife, where some of the most important things we do, from parenting to neighbourly kindness, don't earn a nickel,the answer is a little hard.

In the world of Facebook and Twitter,asin business in general, making money is essential. But it may be that for long-termsurvival, being useful is far more important.

• Facebook revenue beats estimates as mobile ad sales surge
• Twitter reports drop in users, but profit beats forecasts

It seems overly ominous for a company thatdid better than financial experts were predicting in this week's financial results, butsome people are talking about Twitter coming to the end of the line, going the way of Myspace as a takeover target of someone much bigger.

Shredded tweet

That's not what everyone expected when the company launched its shares back in 2013. As an alreadyfamiliar household name, Twitter was supposed to follow the tech startup pattern and soar like Google and Facebook.

Upon its results a day after Twitter,Facebook roared even higher as the company goes from financialsuccess to success.

But despite the difference between the two companies, there is something that both have to worry about: falling out of fashion.

A book I never tire of telling people they should read, Robert Putnum'sBowling Alone, marks the postwar decline of socializing in groups. He points to a pile of research that shows havingreal friends and knowing yourneighbours makes you happier, healthierand longer lived.

Friends versus 'friends'

Unfortunately, he says, it is hugs and smiles and personal contact that makes the difference."Friends" don't count. Neither do "followers."

The social interaction of Facebook, Twitter, Redditand the like must satisfy some of our community-minded urges. Otherwise we wouldn't spend so much time using them.

And if social media can be blamed for increases in gonorrhea and syphilis, there must be at least some contact between "contacts."

But as atriptych of excellent interviews yesterdayonCBC Radio's The Current remindedus,it's possible to get too much of a good thing.

Twitter has many uses. Loved by many of us in the media, it can be shaped into a personalized wire service where you are constantly being updated with the freshest news in yourareas of interest.

But it can also be like drinking from a hose, as loyal followers with too many links become so overwhelmed with information that it squirts out theirmetaphorical noses.

Useful and wasteful

Facebook users say it is great for keeping track of friends and family you don't have time to phone or visit regularly, and provides a wider sample of views and media recommendations. But as a neighbour told me yesterday, she fears her university-aged daughter wastes too much time on Facebook, looking for gossip and tracking down old boyfriends, without too many redeeming benefits.

Research by no less than the U.S. Federal Reserve agrees with my neighbour, according toPeter Reiner, professor at the National Core for Neuroethics at the University of British Columbia.

"What they noticed was that the productivity of workers was rising for quite a number of years and with the introduction of computers it continued to rise until social media showed up," Reinertold Anna Maria Tremonti on The Current.

"It has been flat since social media became so popular," he says."And they attribute it directly to social media."

And like the old-fashioned TV that your parents always said would rot your brain, attracting hours of eyeball time is the way "free" social media companies make their money says TristanHarris, who formerly had the wonderful-sounding job of "product philosopher"at Google.

Intentionally addictive

Like gambling machines, he says, the business ofsocial media is built to be addictive.

"So long as the core business model of the internet is advertising, specificallyengagement-based advertising, then if I can get eyeballs staring at rectangles for long periods of space and time, that's how I make money," says Harris.

But there are early signs that may be changing. Harris is part of a movement he calls Time Well Spent, that aims to turnthe tapandreduce the flow from the hose. He wants tomake social media and the entire internet a tool we use when we need it, and leave the rest of our lives for living, maybe by paying for what we want withcashrather than eyeball time.

A young and tech-savvy relativeI often quiz on such issues has a fairly distant relationship with social media. He is signed up to most of them, but uses them each for specific purposes. As he pointed out, for a busytechnologically aware person, there is too much information out there, not too little.

The internet and all it offers is new enough to be like a candy store. But like theice cream counter and all-you-can-eatchips at the university cafeteria, it takes a while to realize too much is unhealthy.

It may be that social media will go the same way as junk food,wherea little bit is more useful than a lot.
