In my opinion and the opinion of many, Klout is a game of online manipulation and popularity. There is no indication that Klout measures influence. However, it is clearly seen that the once respected Klout score is now measuring popularity, supports spam and gathering information to enhance their Klout Perks program.
Influence is not: The number of friends or followers you have, the number of retweets or replies, likes and comments you receive. It is not the number of posts you write, nor the number of blogs and subscribers you’ve gathered. It is not your page rank number. It is not the number of Stumbles, or your job title. It is not the number of books you’ve read or written, and it is definitely not the your Klout Score.
