I first saw this in Future Social Media group in LinkedIn and in Mashable, and thought it was so good as a wake up call, that I wanted to pass it on here. This great video is by Erik Qualman, here’s his blog http://socialnomics.net/
I’m not subscribing to all the figures and facts of this video [see the comments in his blog to learn more], but the video makes you think over things, and I believe that’s the most important thing.
