But I suspect there is one glimmer of hope on the digital horizon. Boredom with FB and SM generally. Remember its only been going a very few years. Most early adopters are still in the same generational era as they were when they started amassing 'friends'. What's going to happen when they decide to 'unfriend' cohorts of people they probably can't even remember? What's going to happen when they become less and less interested in a picture posted that includes them? What's going to happen when they are no longer interested in mating with everyone (applicable)? What's going to happen when they get jobs and don't want their work colleagues (new friends?), least of all their bosses, to mix with their past lives? What's going to happen when they hone down their lives into the way most adults live - selectively doing the stuff we like, with the people we really like. Privately.
And if 'Business' is as successful as it's planning to be in exploiting 'Social Media', won't we smell the coffee and slowly abandon it as it's fakeness becomes more and more exposed?
