Facebook Comments Box Plugin Comes to Mobile Sites

By Stan Schroeder at Mashable Social Media: 
Facebook has launched Comments Box for mobile, making it easier for users to interact on the site when browsing on their mobile device.
Installing the plugin is simple: if your website has the Comments Box plugin installed, the mobile variant will automatically appear on the mobile version of your site.
The comments can be moderated, and Facebook is using a special “social relevance” algorithm to detect the most relevant comments for each user.
The Comments Box, argues Facebook, is useful since it’s adding to the quality of the conversation as well as social relevancy and social distribution. Facebook’s best practices for implementing the Comments Box on your website can be found here (PDF link).
Facebook has recently been focused on improving user interaction on third party websites. In December 2011, Facebook launched the “Subscribe” button for websites, allowing visitors to begin following updates from journalists, celebrities, politicians and public figures.
