Why did Facebook open itself up to the entire world? I thought that the very specific thing that made Facebook unique was the fact that it was a network for University students.

Now it's not.

Doesn't make sense to me. Do they think that by opening Facebook up to anyone and everyone, that they could compete with MySpace? They pretty much can't at this point. And I think it was silly of them to get rid of the one factor that made them unique.
