All day, every day! I work for a team of people that have been together for over 20 years in some cases, with a few people dropping out and a few people coming in over the years. We've always hung out in an IRC channel as our main form of team communication. Initially because there wasn't any other workable option, and now because it's what we've always done and it works for how our team operates.
