The issue of Rooms is a big deal we have to deal with over on ME.
If you are going to put in rooms, Quality is your main concern. Quantity has no place in public rooms, since if you have more rooms and few users, its going to make it seem like it has less users.
Also putting rooms, you have to put out some tough love. I'm not saying people suck at art, I'm just saying you need to make sure you have a fine line on what you want in a room and what you don't, else it could make the chat look bad.
I hope that makes sense lmfao ;o
