1. Makes communication (especially when employees work remotely) very simple. Great to integrate things like GitHub and Twitter to keep track of updates. 2. Channels, integrations, also integrating with other teams (I'm part of a Slack channel with a company we're collaborating with and it makes it a lot easier to work on things rather than Skype or email). 3. Word-of-mouth, free 4. Too many channels, can turn into a "Facebook" vibe after a while (once you get "fun" channels that aren't work related). I had to "leave" a bunch of channels today and it's quite controversial to "leave" small channels on a small team... But the noise!
