Four Years In, is Klout Working? Your Guess is as Good as Mine:
"Here’s an embarrassing disclosure: about a year ago, my annual bonus became tied in part to Klout. .... So why am I embarrassed about this objective of mine – one I imagine is now the standard for plenty of other employees, across a range of industries? Because four years after its founding and despite $40 million in funding, it’s just not apparent that Klout works very well."
That's being kind. Klout works very, very poorly.
I question the reasoning behind why Klout needs to exist -- Pagerank for People.
If this were actually a good idea, Google would be working on it.
When/if Klout disappears, no one will miss it. Except maybe its investors. Maybe.
