I dont think nerds are unpopular at all, there are billions of nerds in the US alone, let alone the world, who do you think spends money on star wars tickets and helps make them among the highest grossing movies of all time?, jocks and cheerleaders?, hah, who do you think runs video game companys? And lets not forget the great nerd rock movement, Aka Prog.
I love star wars, video games and prog, so i must be a nerd.
