Activities are the next social media gold mine. Google Schemer, pictured above, " is an invite-only Google service for sharing and discovering things to do. 'A scheme is any activity that can be done in the world, whether it's ordering a favorite dish at a restaurant or snorkeling in the Caribbean with sharks,' explains Google." Or you might be interested in EventGrabber, which scans the environment and finds local events for you to do, as described by Mashable. "The EventGrabber team finds and grabs most events from Facebook, and then from local radio stations, online newspapers and magazines and other external sources."
