I'm sure Marc has his reasons for not having one.
Also, every time the subject comes up, you get a dozen people, who wouldn't use it,
who come in and tell you why it'd be a bad thing. How it would affect them, I dunno,
but they like to make sure they speak up and say "don't do it, Marc"
I'd love the idea of a large, realtime chat... and I feel positive that if one were added,
it would be very popular indeed... as chatrooms
always are, "when tied to great websites".
I'm sure also, among other things, that it would be a moderation nightmare, and that
may be a very valid reason why we don't have one here at RCU.
There are a couple of IRC chats that I know of... but they aren't backed by huge
websites, so you end up with very few people, most of the time.
