Research by Hitwise suggests that Facebook has become the fourth-largest distributor of online news content, behind Google, Yahoo! and MSN.
That means that, increasingly, we are deciding what news to read online based on what our friends recommend. Our friends -- and we, to our own followers -- are becoming the gatekeepers who determine which news outlets get the audience.
