Try signing up for last.fm and joining discussion groups. I'm in a couple of those. They don't get used very much, but you can find some good information on there. It's not a bad way to whore your music tastes around either, if you're into that sort of thing. If you're also into that sort of thing, try recordnerd.com, you can put your record collection on there for whatever reason you want to use it for.
