If you look at all the chat rooms on SE, (notwithstanding the temporary ones between users etc) they pretty much all have a) a witty name, and/or b) some following subtext, e.g. :
The Frying Pan: Sometimes hot, always heavy. (cooking.SE)
Literature: Read any good books lately? (literature.SE)
Many of them have a generic "General discussion for XXX.stackexchange.com" subtext.
Ours is blank. Can we set one? Suggestions as answers, most upvotes after a week wins?
