Nerd here, too. Though, looking at the Venn diagram so kindly provided a few pages back, I see that I have moved from the dweeb side of nerd to the geek side as I have gotten older, I think. Did Comp Sci in HS and college along with a math ed minor, though have never been into the video game or sci fi/fantasy stuff. I am, however, obsessed with some off-beat technology-related interests. Never been into the pop music of my own generation, being more into classical music and the music of my parents' time (30s-40s-early 50s). Still somewhat socially inept in some situations. Though, I do take issue with the definition a few pages back, I am not a fat basement dweller!
But otherwise, yup I'm a nerd.
