That's my new favorite website. I found Klout through a friend. You can link Klout to your Twitter or Facebook. The concept of this website is to see how much you are influencing and are influenced by others. They have topics to help you connect with your friends or strangers. You can make your own friends list or just search for people that have the same topics in common. You are given 5 klouts you can give to anyone you'd like. Everyone is given 5. You are scored and than given perks. Those perks get you free products which you are not obligated to talk about. Klout even cares about people with low influential scores. Anyone can join Klout. So go on over and join!
Head on over to Klout and read more about them.
