Grooveshark Broadcast
Grooveshark has this new feature called broadcast where a host will organize a playlist of music and tons of other people can listen.
Nothing like actually mixing live, but it’s a fun environment. You can interact with the listeners (suggesting songs, up/down vote, etc.)
I’m actually broadcasting right now if you guys want to tune in, mostly mainstream house and trance.

I think the best feature of this is that you get to use Grooveshark’s massive database so you discover a lot of new songs.
