I am a sucker for enthusiasm - anything that involves in-depth knowledge and overly excited hand motions is sure to attract me. I tend to like people who have at least a few very different interests from me - I love getting to learn something new from someone who's passionate about it.
I myself am very enthusiastic about bicycle adventures, singing at any time in almost any place, queer community, building shit, my hedgehog, being a grumpy feminist, NBC's Hannibal, drinking excessive amounts of tea, rambling on foot through Portland streets, attending comedy shows, and doing fun things at which I am not very skilled (rollerskating, instrument playing, quilting, socializing).
I am still pretty into anthropology (my college major), spend a lot of time reading fantasy novels ranging from gritty urban fantasy to the Discworld series, and scifi of all stripes as well. I'm developing my cooking skills at a glacial pace, but anything is an improvement over the mushy stirfries of yesteryear. I speak a couple different languages to varying degrees of "conversational" and sometimes get stuck on a word and can't remember the appropriate English one. I'd be really into meeting any other linguaphiles (whether the language you love is English or otherwise)!
Random facts: I wrote my senior anthropology thesis in college on alien cultures in science fiction novels. I volunteer at the Oregon Zoo. I have SO MANY colored Sharpies.
