I know very little about Facebook. Heck, I didn't even have a Myspace account until a few months ago. But Facebook took it on the chin last week when they announced last week that they were changing the way viewers could access your changed pages; whenever you updated your profile, those changes would be sent to people in your network. Even though the doesn't seem like much of a change [it is the world wide web, you know] users revolted. Well if they didn't like that, they're sure not going to like the idea of Facebook going public to non-students. I'm sure college kids will love it when their mom asks to be on their friends list or whatever they call it.
I'd say, for Facebook, this is the end, my only friend, the end.
