Would be good to have a sentiment about the "room" that could be displayed and conveyed to others. An engagement or virtual clapping would show to others the temp of the room. Also a key thing would be to have a way for a small room to grow to a room of 3 or more. A way to discover new rooms that are interesting would be good. Another thought is to have a time minimum that a person would have to be in a room. While this is counter intuitive it would help provide bouncing and promote a minute or more before making a judgement. I see this as something that would be healthy and prevent room hoppers that never fully engage and a attention currency that is helpful to meaningful engagement.
