I realize I'm late to the party here, but I've affectionately referred to The Ask Ubuntu General Chat Room as "The Water Cooler" as it's where I typically go to find someone who isn't too busy working to help! ;-) Be that as it may, I don't actually see the need for a new name for the room as the current name makes it easy to find. After reviewing something on the order of 5000 posts here, I would hesitate to add another level of confusionlevel of confusion for members (new and old) to overcome.
