You shouldn't ask questions in a chat room because then they are not visible to anyone who comes by an hour later. But it would be cool to live-chat about Q2A with gideon and other users.
I do have a chat room on my Q2A site and am currently converting it to a plugin, which I may well release as open source. It uses jQuery so I'm waiting to see where Q2A 1.4 heads with its javascript...
