Perhaps people are buying into the delights of earnest, giddy enjoyment—the joy of being a nerd. And then suddenly you realize that, in the end, everyone’s a nerd, not just those of us with Han Solo key chains. Did you preorder the next season of Sex and the City on DVD as soon as it was announced? Then you, my friend, are a nerd. Do you faithfully trudge out to each new Jude Law film, hypnotized by that rakish grin? Hello, Jude Law nerd. Do you hotly debate Broadway debuts, haunt the newest eateries, track obsessively the ups-and-downs of your favorite team? One might call you an aficionado, a foodie, or a sports nut. Or more succinctly: a nerd, a nerd, and a nerd.
