Some discussions don't belong even on meta, e.g. when it's pure noise.
But sometimes we want to make some noise amongst ourselves, don't we? At least I know I do. I've only been on Stack Overflow for a few months, but I already felt like I've started to develop some connections to other users, and just want to... chat?
So where can we do this? Is there an IRC/Google wave channel/whatever where SO users hang out where we can just ask, "How's everybody doing today?"
