This article from Wired discusses a new offering by Facebook that lets news websites use Facebook as the platform through which comments are posted. The primary benefit for the websites seems to be leveraging Facebook's network to draw more users to their sites; the primary benefit for Facebook seems to be further enveloping a new area. Right now, Facebook users can "like" or "share" many news articles in addition to traditional comments on the news articles themselves. By completely replacing a comment section with a Facebook-driven alternative, Facebook will have completely enveloped participating news sites in terms of owning the user experience beyond reading.
