This is likely a 10 year cycle going on That's why I say "Maybe the next generation, who grows up watching their parents using Facebook" ... I bet between 2015-2020 Maybe not even that soon. I think things are getting entrenched. The mainstream switches more slowly than early adopters. Until the last few years, it's all been early adopters, and we've gotten used to things changing incredibly quickly. Also, there are strong network effects in play for Facebook, not so much for e.g. Google.
