Klout is a tool. If you use it as a tool and understand its numerous limitations and drawbacks, good for you. Please don't use it for ego fluffing though. If things like Klout make you happy, more power to you. But I do see the whole kind of obsession as more than a bit meaningless and wasteful. First of all, the Klout score is just one company's opinion on an algorithm. There are lots of ways to assign some kind of score to social value. There's nothing inherently meaningful or objective about it. Second of all, even if you're focused on this as some kind of ego stroking thing, the people you're measuring yourself can and do game the system. The number of companies at http://www.buytwitterfollowersreviews.com/ is indicative of that. But generally speaking, there are more productive things in your life to be focused on than some arbitrary score.
