Ok, I figured I had to find out what Klout is about. Could I match Justin Bieber? He has a 100 rating on Klout, rumor has it that he can get free upgrades, restaurant meals, etc. -- the bottom line is that he had klout before Klout existed -- so to speak.
Klout evaluates your online presence in the areas where Klout evaluates your online presence -- such as Facebook, LinkedIn (although I'm not as sure of this), Twitter, Google+, -- yea verily, even Blogger. It looks for followers and friends, but even more for re-tweets, references, etc. When other folks point to your stuff and tell others about it, it increases your Klout. All of which makes real sense.
Once upon a time there was Google, and they made money by associating the things sought (search) with things that could be bought (ads)
Then there was Facebook -- where friends count. Or more specifically, when you "l.ike" something, your friends find out. -- sort of an online "word-of-mouth" recommender system. Logic, folks will take more interest in the things their friends find interesting. [Result -- massive IPO valuation expected.]
Klout is a logical extension of this -- evaluating how influential your web presence is, and assigning it a number. I understand that 50 is the magic target (for those under 50) -- and if your Klout is low you may not get that job, or upgrade -- well let's face it, why treat someone well if their Klout is zero?
So there is a new game to play ... for Klout score ... room for mutual backscratching (I'll K+ you if you K+ me, or I'll cite your blog, etc. etc.) -- and it could make sense, if Klout has any Klout.
For example, members of IEEE (or AMA, or the Sierra Club) could create Klout Klubs, endorsing, recommending, and otherwise promoting each other on Klout. From this both the individuals Klout would raise, and there is the potential to establish visibility for the overall Klout of the organization.
There is the other side of this ... I find that Vint Cerf has no Klout. -- this doesn't make sense in my book. At least Tim Berners-Lee has Klout ... although it seems to have been declining according to their graphing. These are two folks I'd listen to any time they choose to speak.
What Klout misses is the dialog that occurs outside of the "big 10" social media sites. Besides the Reddit, Wired and Technorati sites; there are the thousands of sites where folks interact outside of the public eye. Somehow I think the folks that really have Klout tend to interact there, not on "main street". But, for a certain class of influence (think People Magazine, not Nature) I suspect Klout has -- well, some impact.
