I am married to 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. It may have been an insult to me back in middle school, but 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 role-playing games (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.
Now that I'm used to it requiring absolutely no maintenance, I'm growing it out again, so It's kind of perpetually messy these days.
Other than that, maybe people notice when I'm wearing a t-shirt with a joke from the internet, though I dress up a bit more often lately, as I try to convince people that I'm some sort of "professional" or "responsible adult".
I've been a science fiction and fantasy reader for as long as I can remember. I grew up on Isaac Asimov, J.R.R. Tolkien, and Terry Pratchett, among many others, and into my twenties, Neal Gaiman (Sandman, of course, and American Gods and Stardust, and also the amazing Batman: Whatever Happened to the Caped Crusader?) and Jack Vance were my big obsessions.
These days, anything new by Charles Stross (I am so very much his target audience for the "Laundry" series) or Brandon Sanderson gets high priority on my to-read list. Neal Stephenson's Cryptonomicon is a long-standing favorite, and I also liked the Baroque Cycle a lot. Mike Carey's Lucifer remains my second-favorite comics series after Sandman, and I've enjoyed his other comics work as well; his Felix Castor novels are a fun fantasy-noir blend. China Mieville's Perdido Street Station heavily inspired the setting of my last D&D game.
Godel, Escher, Bach and "Surely you're joking, Mr. Feynman!" are both highly hyped in geek circles, but very deservedly so. David Kahn's The Codebreakers is another favorite doorstop. If you're into low-level programming and early video games, I can't recommend Racing the Beam highly enough. Oh, and go read The Poisoner's Handbook immediately, too.
Movies and TV
Classics: Kevin Smith's early stuff. The Princess Bride (the book's awesome too, in a very different way). Labyrinth. Anything with Muppets in it. Star Trek, Classic, plus most of TNG and DS9. Babylon 5. The American President, Sports Night, and The West Wing. Anything from Joss Whedon
Recent-ish: Agent's of SHIELD. Doctor Who (mostly New Who, though I've enjoyed a few of the classic episodes as well.) Sherlock.
I listed Minecraft in my Six Things. I play a lot of Team Fortress 2 as well.
Past favorites: NetHack, LucasArts adventure games, the Baldur's Gate series, Planescape: Torment, Half-Life and sequels, Portal, Braid, and Bastion
I'm a recovering World of Warcraft addict. I play Hearthstone now, much less compulsively.
I enjoy a bit of interactive fiction now and then. Photopia and Spider and Web are probably my all-time favorites there. I'm currently playing through Hadean Lands.
I like lots of stuff; I'm not much of a diehard fan of anyone.
Here's some quirky/nerdy stuff I like: Rasputina. The Dresden Dolls. MC Frontalot. TMBG. Nightwish. Cake.
I like electronica, but don't have strong opinions on sub-generes or particular artists.
I like musical theater, as well as mash-ups, and a capella or cross-genre covers.
I'm an omnivore, and honestly not much of a foodie, though I can appreciate it when I get dragged to somewhere nice, but not too weird. I like spicy things. I wish I were better at doing interesting things with vegetables. I've come to love sushi since moving out here, though I'm still not super adventurous about it.
Oh, caffeine, why can't I quit you? I'm not a huge coffee drinker (though I'll drink it socially, especially with lots of sugary junk in it), but I drink more Diet Coke than is probably healthy for me.
I loved playing with Lego bricks as a kid, and these days Minecraft fills the "I wanna build a treehouse... or a castle... or a tree-castle!" spot in my heart.
Role-playing games are my main hobby. I'm actually looking for a group at the moment, if you know anyone...
I love reading all kinds of speculative fiction-- everything from blow-your-mind science fiction with crazy premises to ultra-formulaic epic fantasy novels to alt-history, to magical realism...
Chocolate. 'nuff said.
Finally, it's sappy but true: my wife is the single best thing in my life. And I'm not just saying that because she's sitting right next to me as I type this...
The whole polyamory thing, which I'm relatively new to, though I'm sure plenty of poly, gay, etc. people before me have also struggled with these questions: Is this an integral part of who I am now, or can it just be something we do? More practically, do we have a moral obligation to "come out" to friends and family, or is it enough to just abstractly support a poly-friendly legal and social framework?
I'm also very conflicted about whether David Tennant or Matt Smith is my favorite Doctor.
- You value open, respectful dialog about needs and boundaries.
- You're looking for something fun and sexy, maybe fairly casual, but more emotionally intimate than simply friends with benefits.
Of course, if that's not what you're looking for, feel free to say "hi" anyway. I think it's fun to chat with new people, whether or not it looks likely to lead to a date.
Pondering what to say to me? You could tell me about a cool place in the area I should check out. Or you could tell me the worst joke you know. Or pick a match question we disagree on and challenge me on it.
(That said, I will totally respond to a simple "hey there". Go on, you know you want to be lazy.)
