Very cool, I'm tempted to lurk in one of these rooms all day.

It'd be very cool if the chat rooms also displayed an auto-updating list of related questions to the side. For example, if you're sitting in the Ruby room and someone posts a question to StackOverflow with the `ruby` tag, a link to the question would appear in in this list.

Another cool idea would be a way for people to turn their chat questions into real questions on StackOverflow. Obviously copying and pasting works just fine, but I think a built-in feature could improve upon it. And it might be a way to give people reputation for helping others via chat.
