Klout makes its first acquisition: Local-mobile app Blockboard

Klout, the San Francisco-based startup that measures people’s “influence” across a variety of social networks, has made its first acquisition with the purchase of Blockboard, a Twitter-like mobile app that functions as a community bulletin board for posting messages viewable to your neighbors.

Like it or not, the reputation graph is here to stay

Klout, the reputation-ranking service that recently confirmed a new round of funding, may not win the race to create a “PeopleRank” for the social web, but someone is going to do it — because the need to measure online influence is only going to increase.

Is Klout crossing the line when it comes to privacy?

Critics claim Klout is invading the privacy of those who haven’t even joined the service, including children, by compiling “shadow profiles” of them based on their activity online. Is that an infringement of their digital rights, or just the new reality of living our lives online?

Should you care how high your Klout score is?

Users are outraged about changes that Klout has made to the way it calculates online influence, and some argue these scores are meaningless. But measuring “reputation rank” is clearly a huge potential market, and Klout is far from the only one interested in doing it.

What If You Were Paid Based on Your Klout Score?

Salesforce.com CEO Marc Benioff says the company tracks activity on Chatter, its internal Twitter-style social network, and gives employees who provide valuable information via the network extra compensation, in the same way executives are given bonuses for hitting sales targets. But is that a good idea?

Klout Adds Facebook Data to Its Influence Graph

As social networks become more popular, the challenge of finding relevance amid all the noise becomes exponentially harder. Klout, which is trying to build a comprehensive database of social influence online, says it is now integrating activity from Facebook into its service as well as Twitter.
