Facebook has offered blog owners the ability to integrate their commenting system into their own sites for a while now. So fa, it has seen limited adoption, with most sites using their own commenting system, or something like Disqus, and integrating the 'Like' button or Facebook Sharing. Now, rumors abound that the social networking site is about to completely revamp its commenting system, and is set to offer the same functionality that'll allow this much enhanced version to replace the comment system on most blog platforms. Some of the rumored features include threading, comment voting, and the ability to login using Twitter or Google IDs.
