'X' is the next 'Y'
Is Facebook the future? Lots of people like to make predictions about 'the future'. I like to wait and see before I make my predictions. I am a Facebook member but I'm not sure I'd go as far as declaring it the future. It is an interesting experience. I am drawn back in by all the activity, friend notifications, application additions, etc. etc.
But, you still need a username and password to get in. I also give my content away to someone that is not me. It's still a walled garden even though there is an openness for developers to build widgets, etc. That just gets more people in.
All I'm saying is predicting the future is a dicey game.
