Agreed. I think it has it's place, like, "we, a select and small group of people are doing this thing together right now and need someplace to chat about it in real time" or for very small groups of friends/family as an alternative to occasional group text messaging.

But, when I see FOSS teams use it as their primary mode of communication with each other and users, with multiple conversations going in parallel and talking over each other, I'm dumbfounded. How do they find that productive?
