Say what you will about Klout (and I am sure someone will have plenty to say about it for sure) but they are making progress in tying a measure of social media impact with Perks for those who ‘measure up’.
The latest offering is actually pretty interesting. The Klout blog explains
Today we’re announcing a partnership with American Airlines that gives Klout users access to nearly 40 worldwide lounge locations including San Francisco, Dallas, Los Angeles, New York, Tokyo, London and many more. Starting today, if you have a Klout Score of 55 or higher, you can gain access to the Admirals Club by going to aa.com/klout. You do not have to be an American Airlines passenger to be eligible for this Perk.(emphasis added)
