We just pushed our first two patches:
1) After loading broadcasts, you're immediately shown the live broadcasts. A lot of people seem to have dropped out before actually trying anything
2) The exit key is now a bit yellow, hopefully this will bring a bit more attention to it. It seems that no one actually knew how to leave a broadcast. We'll probably also change the icon or text for it
3) You get a notification in the chat if your mic is on
4) Hopefully-maybe-possibly fixed the audio bug some people experienced: where they couldn't hear some other users but other users could hear them.
