LinkedIn has acquired news alert start-up Newsle in an effort to bring a Google-alert-like real-time news notification to millions of professionals networking on the social site. The major product of Newsle “scans the web to find blogs and articles that mention specific people and then return results that are relevant to those connections”. So expect to see all your former co-workers’ recent achievements blowing up your LinkedIn news feed. As LinkedIn expands it positioning from a mere professional social network to a sophisticated, multi-faceted digital career fair, it is a smart move for them to continue buffing up their news platform. Not only would it help retain users by establishing LinkedIn as a go-to site for daily consumption of professional news, it could also potentially function as a platform for some native advertising within targeted professional circles.
