If forced to pick a label for myself I choose dork (that's because I have no spatial awareness and can fall over my own feet without trying). Though others would say geek - my OH does say I'm a bit like Firefly's Kaylee.
I've always been geeky/dorky - I was a big bookworm as a kid and loved playing all sorts of pc games. I still love books (sci-fi, horror, crime, manga) and I still play pc games. I've been a big sci-fi fan since I discovered The X Files way back when it started more or less ( can't believe that show is 20 years old now). Since then I've become a 'Gater (yes I even went to GateCon one year), a Firefly fan and other things.
