Klout

Your Klout score shows, on a scale of 1 to 100, how much clout you have in your social online spheres. Klout scores are based on a number of factors, explained on the company's website.

In addition to providing a score on a scale of 1 to 100, Klout also places you on a matrix that shows how you're influentials. I've been dubbed an "influencer," not quite reaching the ranks of "expert."

Klout tells you how many topics you've become influential about as well as what they are. I, for example, appear to be heavily influential when it comes to iPhones and bagels. Go figure. I do love them both.

One thing Klout's score analysis is how your influence and patterns of connecting online change. The big dip in my graph, which shows July 1-18 (beginning of current month to date), corresponds to three days when I was out of town unexpectedly, and hence largely offline.
