I came up with this idea when thinking about this question. I made a chat room for it, as a convenience to other users who may be interested in doing local in-person meetups, as that seemed to be something the OP was interested in. (And heck, I'd find it interesting, too, to be honest.)
I had to go back later and add a comment with the chat link, because I rather embarrassingly forgot to mention the link when I created the room.
It seems to me that the UI should include some form of automatic link if someone has created a room off a question.
(Yes, I'm aware of the irony of the guy who was vehemently against this feature making a request to simplify its usage.)
