I want to tee off the two words you cite as motivating this proposal: 'coordinate' and 'socialize'.

Coordinate

When your development team sets out to coordinate, they all start with one critical common premise about what they are coordinating: "We work for Jeff." I'm sure that there are disagreements from time to time; I certainly don't mean to accuse you of running the corporate equivalent of HMS Bounty. My point is that there is much, much, much more common understanding of the goal of the effort in your team than there is in the entire so.com community, or even the 10K subset thereof.

I fear that an IRC channel or any of the other mechanisms discussed here will mostly deliver fuel and oxygen to the disputes about subjective questions, editing, and question voting (just to name three).

The structured Q&A format of meta serves as a set of control rods in these reactions. People post up their views, there are comments in tiny print. Nothing is resolved, but the clumsiness of the whole business seems to me to impede the inevitable rush toward name-calling.

If this thing existed, my most frequent post might well be: "Quick: question X is open for deletion! Let's go get it before they finish reopening it!"

I suspect that this, and it's mirror image, are not going to lead to building a happier community.

I could summarize all of this under the general description of "Snark Fin Soup."

Socialize

I could see some socialization at the 50K level. People who invest the time to get really high rep put so much time into this that they are prone to feel like they want the moral equivalent of the local VFW hall in which to swap stories and compare wounds. Below that level, my personal opinion is that the various denizens don't have enough in common.
