We all know about the idea of the overweight, basement-dwelling virgin, the idea that gamers and comic book nerds all look like the comic book guy from The Simpsons. Many of us know that is not the case. You even see people in trade chat calling each other "nerds" and "virgins," although the inevitable response of calling someone else a nerd in WoW is laughable. In my guild alone, we have a lawyer, an author and a chef, along with many happily married people with children. Some are openly proud of their nerdiness; some try to argue they aren't nerds over Vent.
My girlfriend hides her geek from a lot of her friends. She watches anime, is a gamer and even dresses up for our local comic book convention, but many of her friends and work associates have no idea about this side of her. Me, on the other hand -- I let the geek flag fly. I wear my gamer T-shirts. I talk openly about WoW and other games with my friends. I still complain about the fact Firefly never got a second season.
