hahaha! I think nerdiness is in the eye of the beholder, and I think it's 90% personality and 10% appearance. Brad pitt would be a nerd if he spent all day talking about his compo. So I personally don't judge anyone here by their appearance. You could all be really cool cats and be fun to hang out with.
I think you're only a nerd if there's no balance in your life. I have mates round and have flippin LAN parties, and I play with remote control cars, and I program computers and write music. All nerdy stuff. But I also have girlfriends (only one at a time sadly), go to pubs and clubs etc. I never talk about programming, compo games or RC cars unless the person I'm talking to is into them too.
On the flipside, if all you do is code/play compo games and not much else, you probably are a nerd. But I think that extends to everything. If someone is a blackbelt at kung fu, but all they do is talk about kung fu, then in my eyes they're a flippin nerd!
And I like a bit of football - it's supposed to be a masculine cool thing to do - football football in the UK. But when you get somebody who is obsessed with it and will prey on anyone who likes football a bit to rave on for hours about the latest Chelsea signing ..... that's a serious nerd if you ask me.
If you can't shut up about what interests you when its appropriate, and you pretty much are only interested in one thing, then you're probably a nerd.
... which is ironic, cos I've just babbled a load of boring crap at people who don't care for about 10 minutes.
