I'm not *obsessed* with music, but maybe I'm just fooling myself. I love discovering new music, reveling in old classics, and realizing that music I passed over fifteen years ago is actually pretty damn awesome.
I enjoy games of almost all sorts, video games, board games, roleplaying games. I love the outdoors, and keep meaning to do more hiking and camping, but never feel like I do enough.
I'm a vicious infovore, few things make me happier than learning something new (except maybe a new set of LEGOs or discovering an awesome band). As such, I'm open to new things, but I might need some pushing to get there. This sometimes leads my friends to drag me out, if somewhat unwillingly, to try new things.
When it comes to work. By day, I'm a not-precisely-mild-mannered software engineer. (Ok, technically I do PHP Web Application Development, but I'm desperately trying to focus more on the back-end/server side PHP framework code and less on the front-end html/css. The last thing I want to be is a css-jukie.
Programming (when I'm not daydreaming of The Next Big Thing™ to develop).
Procrastinating (usually the above).
Making awful jokes (though sadly, puns prove difficult for me).
Making White Russians.
Drinking Gin and Tonic.
Playing awesome Board Games (Agricola, Dominion, Race for the Galaxy, 7 wonders).
Anything by Douglas Adams, William Gibson, Neil Gaiman, or Neil Stephenson. The Wheel of Time series is a (somewhat embarrassing) favorite. "An Enquiry Concerning Human Understanding" is one of my favorite Philosophy works.
A handful of movies I'm fond of: Sneakers, Hackers, Pi, Chasing Amy, H2G2, Eternal Sunshine of the Spotless Mind, Lost in Translation, Pulp Fiction, Reservoir Dogs, Pirates of Silicon Valley, Sideways, Garden State, Hudson Hawk, Serenity, Raiders of the Lost Arc, M.A.S.H
There's a lot of good television, and even more bad, I tend to enjoy good science fiction series'. Some relative "classics" I'm fond of are Babylon 5, Farscape, Daria, Firefly, Robotech/Macross. Lately I've been really into Doctor Who, Eureka, Leverage, Big Bang Theory, and How I Met Your Mother.
Anything (practically). Discovering new artists/bands is like getting a new set of LEGOs (and I LOVE Lego). A few of my perennial favorites are: Natalie Merchant, The Weakerthans, Queen, Rush, The Get Up Kids, TMBG, Guster. http://www.last.fm/user/duaiwe/charts
Food: Pasta is always a favorite (Lasagna or Manicotti), though I've become quite fond of Phở. Well made tacos are divine.
Game design, philosophy, ethics, and other lofty things that rarely go farther than some half-thought-through internal monologs.
Why the rest of the world is so frustratingly stupid.
What book to read next.
A better way to do.. everything.
Also, I have a probably-unhealthy obsession with 'We Didn't Start the Fire', by Billy Joel. I'm *not* ashamed of this.
