This is my second time on OKC. The first time around, I met and eventually married the lovely and charming seriphel. We've since decided to pursue polyamory, which we try to practice with honesty, empathy, and lots of communication.
When asked to describe myself, I usually fall back on saying "I'm a total geek." Nerd/geek/dork - I'll cheerfully answer to any of those; I've long since decided to embrace it.
True to form, i'm into all of the stereotypical geeky stuff: computers (programming, playing games, endlessly swapping out parts), reading (though my attention span for Serious Books is not what it once was - I blame the Internet), and Dungeons & Dragons (ask me about my username!).
Beyond that, I like deep conversations about things that are interesting (which is pretty much all the things). I like learning about stuff I don't know anything about, and exploring new places I've never been, especially if I have a partner or a guide.
In terms of politics and philosophy: I'm a skeptical agnostic secular humanist militant feminist egalitarian progressive liberal utilitarian libertarian. I see no contradiction there, but if there is any, well, I think my buddies Whitman and Emerson have got my back.
 It's tempting to try singing that to the tune of "I am the very model of a modern major general", but it doesn't quite work, alas.
 I'm not actually friends with any 19th century poets, but, you know, I'd like to think they'd totally be cool with me name dropping them to impress people on the internet.
I'm an introvert. That's not to say I'm a shut-in! I like people and going out and doing things with them, but I do prefer small groups to huge crowds, and I need a fair amount of alone time to recharge too.
My sense of humor is about 60% fluffy goofball absurdity, 35% cynical sarcasm, and 5% totally twisted.
