Klout is social influence measuring tool that determines based on a variety of factors how influential you are in your network.
I have recently discovered Klout for myself. After adding all the social networks I am part of, my score is only 26. According to Klout I am a Conversationalist.
Klout is an interesting analytical platform that works with your current network; based on how many people you interact with online, Klout measures your True Reach, Amplification Probability, and Network Score.
The final Klout Score is a representation of how successful a person is at engaging their audience and how big of an impact their messages have on people.
More and more employers look at the Klout scores of the potential employees.
It is an interesting analytical tool and I will be looking forward to its growth. Also will be interesting to find out of someone ever tweaked their score and cheated on Klout.
