Once upon a time we would have DJ sessions using turntable.fm, but then that died and we couldn't find a replacement. Maybe we'll have to set up a Hubski channel in plug.
We started on turntable too! Our weekly Wednesday themed events have been going now almost 4 years. Here is a good sampling of our history if you can't make the weekly events. https://www.youtube.com/channel/UCgJDCYu0n9UhPS_jcbOurRQ/playlists
UPDATE: I've made a hubski room on plug.dj They've made a lot of improvements to plug as of late, to the point that it works better now than turntable did. The UI does take a bit of getting used to. I find the backgrounds pretty unfriendly to the eyes, but use something like pluggedN for Chrome and you'll get custom backgrounds and auto-woot features.
