I love this video by Eric Berlow from Ted Global 2010. When I saw this the only thing I could think about was this was so much like a social network. In the social media industry today so many people are looking at communities as individual transactions and not as a complex system.
Until we get out of this mode of thinking in old school web analytics and treating this as only an engineering problem, we will not be able to fully get our arms around social media. What do you think? Are you looking at your networks as a larger system?
