Social network and marketplace for photographers

Selfie much? EyeEm is a free photo-sharing and discovery app for iPhone & Android. ... EyeEm is where a global community of photographers are defining a new generation. (Germany)
@davemcclure thnx for the mention, Dave!
I use EyeEm for photos. The geo-tagging is linked to Foursquare and works the way Instagram used to work before they started using Facebook location data. Now I mostly use Instagram for videos and EyeEm for photos. Also EyeEm integrates stock photography submission right into the app. So far I've sold 10 photos via EyeEm.
