It can't be generalized like that.
I guess others do see me as geekish/nerdish, but I've never really thought of myself as a real geek. Dunno, I have (or at least used to have) lots of different interests and I know a lot of (quite useless) stuff that very few others know (and will probably never need in their lives, so I can't blame them), I was among the best students at high school (although I was really studying very little), I used to play video games and knew a lot about computers but in the last year or two I lost interest at that (but still many friends contact me when they have computer problems)... Well, I do lack social life. It's not that bad, I have lots of friends, but I don't really have any 'best friends', those that you normally spend every weekend with and stuff like that. I go out every now and then, get drunk, visit almost every gig of local cover/demo bands... but when you sum it all up, I spend most of my time here, in this chair... It does bother me a lot, makes me very depressed often, especially since I have some interests and there are lots of things I'd like to own, do, try and/or learn but there's no way since I live in a poor third world country which is like at least 20-30 years behind the western world, and I'm... ok, I'm not really poor for our standards, but compared to an average family in the western Europe, I'm very poor. I do feel like I'm wasting my life.
Most of metallers here are different; metal is normally considered as "extreme music for extreme people" here. They're not really extreme, but most people are kind of outcasts, bad students who go out every night, get drunk often...
