Yeah chat would be cool. I’m down with seeing some ongoing discussions. As it stands, GovLoop (and a lot of websites, really) sometimes seems like an empty restaurant–it might look inviting, but without customers in the seats, people are more apt to pass it by. Chat might give more credence to the “life” of the site.
Feature creep is a problem, sure. Maybe if chat functionality were built into “discussions” in some way.
