I'm often asked what the +K is on some of my posts on Twitter. You can give bloggers who influence you a +K for different topics that they blog about, but that is only a small part of the overall Klout score. One of the things that Klout does do is raise the profile of your blog with PR companies who might then ask you review appropriate products. If you are interested in joining Klout to see how your score compares, you can find it at www.klout.com. There are lots of other sites that also measure influence.
I have chosen this for today's theme 'Reaching Up' as True Reach is one of the factors that Klout measures.
