Yeah: I am actually old enough to have been waiting for Facebook to be supported at my University ;P. I remember it already spawning with the same functionality of, say, Friendster, and so it already was based on the "social network" concept of people having "walls" they posted to and the concept of "friends" that you were thereby keeping up with... which frankly isn't anything like a "bulletin board" (virtual or physical) and was much more like people posting stuff on the door of their dorm. It could be that it was a bit different, though, in the first handful of institutions before it got around to supporting mine.
