Google Buys Automated Friend Manager Katango

Google has acquired Katango, a start-up that analyzed Facebook friend lists to generate lists of related people so that users could better segment their social networks. Since Katango launched, both Google+ and Facebook have introduced similar functionality (though not as automated as Katango), so an acquisition by Google seems like the best possible outcome for the start-up, which had raised $5 million from Kleiner Perkins.
