Busyflow supports a variety of cloud applications, including Dropbox, Google Calendar, Google Docs, Pivitol Tracker, Google Tasks, and Github, with plans of adding Basecamp and Yammer soon.
The service provides a newsfeed of all the activity going on in your teams apps, and gives users a wall for each project to discuss issues with your team. Busyflow calls each of these workspaces a Hive (going with the bee theme). A free plan allows three users and one hive and at the high end, the Unlimited plan runs at $3/user/month.
If you find yourself wishing your team could more easily interact and communicate about cloud services, BusyFlow may be worth checking out.
