5 Ways to Cultivate an Active Social Network is a nice infographic by Mark Smiciklas at Intersection Consulting. Although not conveying a lot of data, this does a nice job of visualizing the five different activities that Chris Brogan advocates to build and maintain your social network.
This marketing visual was inspired by Chris Brogan. Check out his original post: Cultivate an Active Network.
