Facebook may be looking to update its commenting plugin with a slew of very important features, including threaded comments, voting and more.

If the screenshot is genuine, it's extremely interesting; the new features have the power to transform Facebook's commenting platform for third-party websites — which is currently a very simple affair — into something far more advanced.

All Facebook has a screenshot (below), which shows these features in action:







Threaded comments are a great addition; many blogs, including Mashable, have switched from a single-threaded to a multi-threaded commenting system and never looked back. The ability to see some extra info about the user that left a comment, including his comment count, is obviously quite useful, too.

But the really big news is the voting system, which gives users the ability to rate a comment positively or negatively, similar to Digg's voting system. The votes result in a comment rating, which can be really useful if Facebook plans to introduce a comment moderation system based on the ratings later on.

We've asked for Facebook's comment on the screenshot above, but haven't yet heard from the company.

What do you think about these new features that may be coming to Facebook's commenting plugin? Would you like to see any other improvements? Please, share your opinion in the comments.
