Anyone may follow my public tweets. Friends may request to follow my private tweets. I've also syndicated my public tweets on this site using a Twitter block for concrete5 which I've been working on.
Friends are invited to friend me on Facebook. I've been developing some Facebook applications and digging into their new social tools, which are quite excellent.
Colleagues can find me on Linked In. I also have a Google Profile, although as I'm the only Matt Pavelle on the planet (as far as I know) there is little need for disambiguation.
I'm a member of the Association for Computing Machinery and the IEEE. And as a devoted Linux advocate, I'm likely to be found at the local LUG.
And finally, a nod to my alma mater, Carnegie Mellon University, specifically the School of Computer Science.
I read books of any kind on any subject matter. If you have the means, I highly recommend the Kindle 2. If you own one, you may download and read most books that are out-of-copyright for free on it thanks to Project Gutenberg. Very slick.
I'm interested in anything technical or scientific, in any field whatsoever. I can't possibly add enough links to my favorite news sites (my RSS reader is frightening), but here are some of the magazines and websites I subscribe to or frequent: Scientific American · nature.com · Seed · Science/AAAS · Wired · Slashdot · Science Daily · New Scientist
I play Texas Hold'em Poker. In person, not online. I mostly play at The Poker Rooms in Florida at the moment.
I'm obsessive about exercise. I was studying Bikram Yoga for a while, but now I'm into any Hatha Yoga. I'm working towards running a marathon this year. Lifting, swimming, golf, tennis, etc.
I enjoy games. Board Games: I love Chess, Scrabble, Trivial Pursuit, Backgammon, etc. I'm a big fan of the New York Times Crossword which I play daily on my iPhone (great app btw). I've enjoyed some computer games but it takes a really good one to get me hooked.
A few of the organizations I support include: Electronic Frontier Foundation · American Civil Liberties Union · Creative Commons · Doctors Without Borders · SETI Institute · American Atheists · Natural Resources Defense Council · National Audubon Society · Appalachian Mountain Club · Renewable Energy Policy Project · Kiva
