Social network influence-measurement service Klout doubled its pleasure by doubling the total number of networks it factors into its ratings system, announcing the addition of Blogger, Tumblr, Flickr, Instagram, and Last.fm.
The five new networks joined YouTube, which was added earlier this month; foursquare, which became part of the mix in July; LinkedIn, which was added in June; Facebook last year; and Twitter when it first debuted, which was three years ago Wednesday, according to Mashable.
Klout uses rating algorithms and other semantic analysis to determine a score reflecting how users of social networks are influencing their followers, incorporating elements such as likes and comments in Facebook, and tweets and retweets in Twitter.
Klout CEO Joe Fernandez discussed the new additions with Mashable, saying:
The networks we launched today were chosen to give the Klout score a more holistic view of influence. By adding blogging, photos, and music to the interactions that we are already measuring we are moving closer to our goal of providing a complete picture of your influence.
On Last.fm, the amount of activity a user or listener generates on their profile will almost certainly be a factor. Tumblr is a great example where re-blogs and love are clear signals of influence, and Instagram provides likes and comments.
We are eagerly anticipating (Google+) launching its API. As soon as it makes the data available, we will be ready to add it to the Klout score.
Today is actually the three-year anniversary of Klout, and we wanted to show off the power of the platform we have built here. The fact that we have launched eight other services — with five today — in the past three months is a testament to the hard work our team has done building a platform that can easily ingest any signal of influence.
And from the announcement of the addition of the five sites on the Klout Blog:
One of our most requested features is blog integration, so we’re excited to be adding both the largest blogging platform in Blogger and one of the fastest growing in Tumblr.
Online images continue to play a huge role in keeping us connected to family and friends while helping us understand what’s going on anywhere in the world; today we’re adding the Godfather of photo sharing, Flickr, and the hugely popular mobile app, Instagram.
Finally we’re adding Last.fm, so we can assess the influence you have on your friends’ listening habits and music discovery.
