What do I need that for for my open source project? I could probably get github notifications, or bugs, or something via a bot in IRC if I wanted, but I just don't see the need. Chat is by its nature not supposed to be the hub of an open source project, because it's a real time thing in a distributed group of people who may not be able to do real time.
Those things can be kind of cool for a company, but when I'm hanging out, on, say #postgres, it's to ask a question or discuss functionality, not see pull requests roll through the screen.
