I’ll let the video after the jump do most of the talking on this one but RunKeeper has improved its sharing service by building out a cool run sharing service that works like a social network for the preternaturally skinny yet surprisingly hungry.
The system allows you to share runs with friends and/or strangers. You can turn off maps for privacy and selectively share runs with the world. For example, I have one visible activity while RunKeeper founder Jason has like 5,000 (actually 130). This means he is better than me and, in fact, better than most of us.
