I am a sucker for enthusiasm - anything that involves in-depth knowledge (of chaos theory or the plot twists of Buffy the Vampire Slayer or the proper declensions of Russian nouns) and overly excited hand motions is sure to get my attention.
I myself am very enthusiastic about bicycle adventures, singing at any time in almost any place, queer community, building shit, my hedgehog (who recently became a grandpappy!), being a grumpy feminist, NBC's Hannibal, drinking excessive amounts of tea, and rambling on foot through Portland streets.
I am genderqueer, not that Okcupid has an option for that. Although my body is coded by the world as "female," I have no internal sense of being a man or a woman - I am a person. I would appreciate not being referred to with female-coded nouns (girl/woman/lady/mistress). If you just treat me like a person, we should get on fine.
Random facts: I wrote my senior anthropology thesis in college on alien cultures in science fiction novels, I volunteer at the Oregon Zoo, and I have SO MANY colored Sharpies.
