Chat is completely open, anyone can join any room and anyone can see the full history of that room. This isn't just development, even Legal and HR have rooms. If you need to have something that exists as institutional knowledge Issues is a good way to go, but we try to hook Chat convos into Issues. Hubot is setup to post comments in an Issue when someone posts a link to an Issue in Chat. Great for looping that synchronous convo into the async stuff. If you need to be more private, in person, email, or Bluejeans is the way to go.
