Many other StackExchange sites have a name for their chatroom. MSO has "The Tavern," SU has "Root Access," SF has "The Heap," etc. Our chatroom here is "Physics." Lame. We need a better name.
I propose "The h Bar."
I add your excellent suggestion "the h-bar", so that people can vote for it :-)
I know I'm late to the party, but I'd like to formally suggest
Schrödinger's Chat - complete with umlaut.
Since our chat room has been named "The Coupling" for a little while, I'm adding that as an option. Vote away.
