After reading http://blog.rescuetime.com/2014/05/14/a-little-hack-that-made-our-remote-team-not-feel-so-remote-anymore/ a great idea came to my mind.
Create separate group (team) chat channel just for “social” purpose where the team members shared stories would flow in. For example new blog post, Facebook, Instagram or Twitter post, Foursquare check-in, etc. Every team member would provide his own shared stories via the services APIs. All stuff would be mainly automated.
I would like to know an automated solution for the scenario of leaving and coming home. Maybe the AFK set by the chat app is the ideal (privacy concerned) solution 🙂
