'The young are still building their social graph and can be more open to new things. So all those things that tie people to Facebook won’t be relevant to kids growing up today.'
I agree. Was talking to a 9yr-old yesterday and he didn't know what a playstation was. Thought he was kidding at first.
I don't think fb can be killed anytime soon though. It's just so big. Migration of half a billion people to another social networking service can't be simple.
