Definition of influence is power to sway. So now explain to me what kind of behavioral change did Klout detect with announcement of Marissa’s new position that could make a case of increase of her influence? I am sorry to say but Klout or any other tools out there were designed and built by engineers  who dont have any understanding of what influence is. No to say that your developers completely ignored any studies published by well recognized names who are researching influence for decades. ie.Cialdini… You said in comment below “We measure influence as the ability to drive action. It was the combination of thousands of people responding to her tweet and the activity around it that caused her Score to rise.” Let’s be clear and honest at least Was not Marissa who made announcement but media outlet, tweets above as well don’t indicate any changes in behavior except expressing congratulation. Congratulation is not really a behavior change, but acknowledgment of an awareness. What Klout is trying to measure is personal power and you are incorporating manifestation of the top of Maslow’s hierarchy of needs. Klout, Kred and others aren’t influencing anything but ego’s of people.
