Today is a big day for Klout. The social influence calculator just added five new networks to its algorithms, bringing their measurement possibilities to 10 total networks. Adding Tumblr, Blogger, Flickr, Last.fm and Instagram to the already-included Twitter, Facebook, LinkedIn, Foursquare and YouTube means that some Klout users are about to see a huge jump in their scores. The staff blog reminds users that “connecting an account will never lower your Score, but it may increase it as we can give you credit for your influence in that network.” TechCrunch notes that Google+ is still missing from the list but that it should be on its way soon.
Klout measures social networking influence based on users’ interactions with their followers and friends, on a scale from 1 to 100. Linking new networks to an account doesn’t immediately improve one’s Klout score, and Klout hasn’t explained exactly how the new networks will be calculated. I’m curious as to how (or whether) Klout will include scores for users who have multiple blogs with Blogger or Tumblr.
