Too diverse to easily generalize, these run the gamut from entertaining drunks to poisonous quasi-intellectuals.
The scornful "art student" type is pretty annoying, with supercilious sniffs at any attempt by anyone to express an opinion about a painting that doesn't include words like "Manichaean" "exegesis" and "transmogrification" in every sentence.

Other than that, the rest are pretty tolerable.
