Yeah, in hindsight Facebook looks especially clever in terms of how they managed their initial roll-out. Going university by university meant that they got to gradually ramp things up infrastructure-wise, and created the I-want-it-because-I-can't-have-it effect that I think a lot of companies go for with phased roll-outs, invitations, etc., but because any given school would get it all at once, as soon as your school got it, most of your peer group would also get it at the same time, which avoided the chicken-and-egg problem Google+ experienced.
