"Do we really need measures of online reputation? Can our worth be measured by the amount of Twitter followers we have or by how many +1s we receive on Google+?
Klout, Peerindex and other social reputation measuring sites are constantly bombarding web users with statistics about their 'true reach', 'amplification' and 'influence'. It all sounds very grand. And yet what is the actual value of these metrics? What does it mean that I currently have a Klout score of 60? This number is calculated among other things, on an analysis of my recent web activity on Twitter, Facebook and Google+ over the last 90 days."
