Flowdock — Chat & inbox for teams

We've fallen in love with flowdock since switching from campfire. The threaded conversations and push notifications on the iOS app are killer features for us.

We use Flowdock at G2 Crowd for team communication. Great integrations with Trello and GitHub as well. My favorite feature is the ability to monitor twitter accounts and keywords. Our whole team can see what we and our competitors are saying on social so we're all on the same page. Plus, of course, funny pictures and gifs to keep things light.
