AIM and ICQ are not "social networks". I can't ever imagine my parents using AIM or ICQ ever. But they are on facebook. Good luck getting them switched over to another service.

Facebook has 500+ mil users. Most of them, non techies.

Friendster actually proves my point...they shot themselves in the foot. Facebook exists because of mismanagement by Friendster.

Isn't it conceivable that the next social network will start as a place for the younguns to get away from their parents? If you were 15, would you rather be at a party with all your friends and everyone's parents and grandparents and aunts and weird cousins or at a party with just your friends?

If that's the case, then the feature set would be focused toward a younger crowd, rather than the privacy features and such that people discussing a "Facebook killer" usually mention. I wonder if it could possibly be a step backwards in some areas.

4chan anyone?

[lancewiggs]

Yes - 4Chan is the new FB. It's deliberately unappealing, it's the new generation. I liken Mys[ace/bebo/friendster/facebook/linked-in/4Chan/whatever to bars and nightclubs. They can get popular for a while, even wildly popular, but eventually they go out of fashion. Those 'pubs' with a slower cadence like Linked-in will take longer to die, but will also never reach the dizzy heights of the biggest 'clubs' like mySpace and Facebook.
