Mine is probably pretty high...but I'm not singularly obsessive about one thing or another..
I have a BS and MS in Computer Science, as well as 3 years towards a PhD...have worked in the software industry for a decade, have 9 computers (2 Linux desktops, 1 Sun Workstation, 3 Windows desktops (98, 2000, XP), 3 laptops (Win 98, 2000, Mac OS X) at home (all working).. have a ton of computer books that I've read. I read Dr. Dobbs Journal, IEEE Computer, and many software blogs every month, but I also subscribe to 6 car magazines and pick up 1 music mag a month (usually Q).
I've dabbled with video games but don't really get into them, but I'm a big music and movie fanatic. Not into comic books (not even much when I was a kid---I preferred reading Car & Driver and Road & Track from about age 7 on). Never got into D&D or other role-playing games, but I love trivia games (NTN, Trivial Pursuit). I don't read sci-fi or fantasy, but have enjoyed some sci-fi movies (2001, 2010, Blade Runner, Gattaca, Minority Report, Dark City, Strange Days to name a few that I liked). I do have the collector gene, though..collecting (and building) model cars and diecast cars.
I go to 2-3 software conferences every year.. I spend way too much time online, but don't have a Blackberry. I love cars, car trivia, but love travel, reading, dining out, museums, rock concerts, etc...
I'm kind of fanatical about maps---before I visit a city, I'll study the street and underground maps in detail.
I'm shy with women, though I've had a few serious relationships--one that lasted 4+ years and is coming apart now, was engaged once, etc. I've tended to date professionals--women that are accountants, software recruiters, software testers, management consultants..
I've always thought of myself as an extroverted introvert..I love my personal time but enjoy hanging out with my friends and cubies...an evening at the pub, a day at a car show, a car club road trip, etc..
