Just read this excellent post on the Best and Worst Things about Dating Nerds.
As a nerd myself, I must agree with the posters complaints and compliments. I have also dated my share of nerds, and even a few hot guy/nerd combos. (Yes hot guys with hot rods and black leather jackets can also secretly collect action figures. The world is a complex place.)
Nerds are fun. I speak as one, so I am biased. But they tend to be creative, thoughtful types, and playfulness is connected to both those things. Writers tend to be a bit nerdy, even the seemingly hot ones. I heart Neil Gaiman, but underneath that leather jacket and behind those big brown eyes is the soul of a comic book geek. And guess what? That just makes him hotter! Do not underestimate the nerd.
