— Facebook unhinged its mighty jaws and continued the laborious process of ingesting the entire Internet yesterday with the blog announcement of Comment Box, a social plugin that publishes user comments made on third party websites to your Facebook profile, and vice versa.

Soft-launched last year, Comment Box is a serious game changer in the world of Internet comments, further connecting third party websites with your Facebook account, portending an Internet of the very near future where even when you leave Facebook for other parts of the Web, you’re never really gone.

Note: Comment Box is a Facebook product built for third party websites. Only third party websites that choose to use Facebook's commenting platform have it. Comment Box is obviously Facebook-branded, so you should know it when you see it.

You'll encounter Comment Box on non-Facebook websites of the near future if you haven't already. You'll find it on many of the TODAY Show blogs such as the The Clicker and Kathy Lee & Hoda. And TechCrunch is experimenting with it right now. You may've already stumbled upon it on a friend’s Facebook profile. Familiarize yourself with this system so you don't go blindly blathering to the world on account of you can’t be bothered to read the fine print.
