Facebook already has a "plugin" for commenting, so I'm curious as to how -- if at all -- this will be different.

Or how it'll be superior to Disqus.

Disqus already has the added bonus of not showing my profile picture to the world.

With the pervasiveness of Open Graph (nee Connect) I'm not sure it'll necessarily have to be "better" than Disqus in order to win its marketshare

And it matches the screenshot in the article 100%.

They also mentioned having not seen mockups. I'd imagine they just lifted the picture from the plugin page, and that the real thing will have much deeper Facebook integration.

This is what I've been wondering ALL DAY.

Facebook once again trying to be the foundation on which all communication and exchange is based on.

For better or for worse is certainly up for debate too. On the one hand, closed systems suck and these valuable comments could get locked out of search engines. On the other hand, I've seen article commenting go through the roof with a simple Disqus include. Ease of sign-in and uniform appearance probably has a lot do with it.

It'll be interesting to see how they implement this.

According to Facebook, they've been testing it on their Developer and Facebook blog. I remember seeing it last week and thinking, "Oh, I've never seen that Facebook commenting system before".

Example: http://blog.facebook.com/blog.php?post=486790652130

Hasn't this existed for over a year now?

Exactly. I really don't know what the news is... Also, having Disqus is better since users can still do anonymous commenting

They should (try to) acquire Disqus.

Do you think that Facebook starting to add more and more features that people might find creepy (it could take a while) can negatively impact its progress?

All the more reasons to comment less on the websites.
