I don't want to derail this thread, but maybe this can become a generic "help anyone choose a new hobby" thread, as I am having the same dilemma. I am quite the hobby jumper, as I have gotten into and then dumped the following hobbies (and their associated gear) over the past four years: manga, anime, Go, Python programming, reading sci-fi / fantasy, WoW, console gaming, learning Japanese, Angband, DJing, pixel art, composing electronica, writing sci-fi / fantasy, imageboards, drawing and competitive fighting games.

I'm at a loss as to what to do with my free time now. Although I've finally established a regular gym/cardio routine, I spend the rest of my free time staring at the internets. Any ideas? Something social would probably benefit me the most, as I don't go out very much. Heck, even hooking up with the local nerds and tabletop RPGing is starting to sound good.
