Best parties I've been to were a healthy blend of web folks, hippies, anarchists, engineers, and discordians.
I did observe that despite having fairly good classical training and historical knowledge--more than I had, certainly!--there did not seem to be a lot of self-educated people who knew physics and hard-sciences beyond a somewhat populist level. I suggest that this may be due theoretical physics and whatnot requiring a sounder grounding in mathematics than is easy to pick up on your own.
