Graphic of the Day: CMO's Guide to the Social Landscape

It's one thing to read data showing which social networking sites are the best for your goals, but seeing all that info in a color-coded, easy to read table... yes, please!  Based on this chart from Daily Bloggr, it looks like Digg and YouTube have more opportunities for social media leverage than the much more talked about Twitter.  I might make a distinction here between the quality of customer communication on Twitter vs. on some of the other sites earning a "good" rating. Would your social landscape guide look the same?
