I am noticing more and more lists (such as City A.M.'s recent Women in the City powerlist) which are based on people's Klout scores. For those of you wondering what exactly Klout is and what is does, this article explains it very concisely. Take heed - in a world of increased personal branding through social media channels I suspect Klout is here to stay.
Klout is a tool that seeks to measure your influence in the online world. It measures both the size of your network across many major social media channels. And it measures the amount of engagement you get from that audience. It is a score that ranges from 1-100. If you have an online profile on any of the major social networks, you have a Klout score.
