I think that one should also differentiate between kinds of nerds. I mean, there's the sort of nerd that reads XKCD, Achewood, Scary Go Round, QC, Dinosaur Comics and Copper, and then there's the kind of nerd that reads Penny Arcade and a horde of lesser immitators. Is one less nerdy than the other? No, probably not, but they are rather subculturally distinct, with first being more 'indie/hipster' whatever and the latter being more 'gamer/haxxorz.'
