Productivity and The Verge/Polygon

After watching Press Reset my interest sparked in what the teams at Vox use to manage their day to day workloads. I managed to spot a couple of tools but if any of the teams could fill in the blanks or what they use and why that would be great.

Products I spotted in Press Reset have been: Trello, Campfire, Google Hangouts, GoToMeeting and Google Apps. What else do you use and why do you use it? Also what do you guys use individually while not working with the team?
