LinkedIn Acquires Pulse for $90 Million:   
LinkedIn, the social network for business professionals, has acquired content curation platform Pulse for $90 million, a move that edges the social network deeper into the publishing space.
Spread across 190 countries, Pulse has more than 30 million users who  have activated its iOS and Android-based news reader apps. More than  750 of the world’s publishers distribute their content through Pulse,  and the app spans nine languages, with 40 percent of its users coming  from outside the United States.
Pulse, which launched in 2010, has given traditional magazine  publishers big boosts: Between July 2011 and January 2012, Bonnier’s Popular Science went from 60,000 subscribers to more than 3 million on the platform, as initially reported by FOLIO:.
