There are so many discussions lately of what makes a person and influencer and a lot of people and brands are swarming around the people they have determined to be influencial. And it's not completely wrong but influence is so much more complex than that. To me services like Klout and a whole host of others miss the entire point by assuming that one person alone is influencial. That is rarely the case.
Fascinating - all pretty new to me yet. Always happy to see complexity taken in to account over simplicity though!
