I don't mean to measure FB by Google criteria, that was mainly a response to what seemed to be a rather vacuous question from the article. Maybe I misunderstood, but people asking "why Google, why now?" in 2002 probably didn't use the internet at all or had a vested interest in some other search engine. I can believe social networking technology will be huge, but I think enough human relationship aspects are mutually exclusive that it will be far more difficult for one service to completely dominate. "Why Facebook, why now?" is a much more interesting question than "Why Google, why now?"
