Someone may have said it, but I'm so grateful my dorm mates didn't have video cameras when I was in college. I never did anything as wholesome as this dancing - though some of it makes me feel I'm watching Cinemax!
One interesting thing is that a number of them appear to be recording themselves (this is judging from the number of cut-off tops of heads and otherwise oddly-framed/odd-angled shots). The stuff that we would have hoped our dorm mates didn't film (and there wasn't much danger in my day, at least, since camcorders were still very new and pretty expensive at the time) this generation is filming and posting itself. I must say, though, most of them are pretty good, and some of them are very good. Some of them strike me as seriously underdressed for any sort of public appearance, but I'm probably just getting old.
