So, you went Starbucks? And you posted it in Facebook, like many other activities you do? Well then, your friends may not only see the typical entry in the news feed, they may also see a “sponsored” story in the right-hand side of the page, with the Starbucks logo included. And better yet (for Starbucks) the sponsored story will not scroll down as the news feed progresses; it will stay there for the duration of your session.
