RE:
Hangout?
:D You can do whatever you like in there I guess. Basically from my experience the best option is normal hangout without streaming to youtube (it's pointless anyways). And I think as long as people are entering regualarly the room will be sustained. As far as time, well I don't know, I usually can tune in in the night, so that's around 12:00 PST I think, but it doesn't matter because the idea is that you can be able to find someone at almost any time on the hangout
