While this is a good move for Facebook's users, who will get a less cluttered feed, it's a disaster for publishers who use Facebook for content distribution. For example, over the past year my company has been supplying news to a network of two million MMA fans on Facebook. With this change it's very difficult to make enough revenue to continue: less reach = less clickthrough to our site = less revenue. The silver lining is that if publishers write off Facebook as a distribution method then perhaps they can work more on other distribution methods, generating some innovation.
