If you're still unfamiliar with the year's hottest social music service, here's the lowdown. Turntable.fm is a service where your avatar stands in a virtual room listening to music and chatting; you can also jump on the decks and play any song in the extensive Turntable library (or upload your own). If enough people hit the "lame" button, the song gets skipped; hit "awesome" and your avatar bobs its head, while the DJ gets points they can put towards a new avatar.
