This, this, all of this. If I get over 15 people in my room, it's a busy night! I have 400+ followers and make use of the "let people know I'm broadcasting" button (CB here), but it doesn't seem to help. Makes you wonder if there's some small thing you're not getting that's keeping people away - but you have no idea what it could be! Here's hoping it'll click into place somehow, someday.
