Facebook like feed question

Hi guys,

I noticed that some website that i "liked" (the main page) now is able to output new articles on my wall. I like this and was wondering if anyone knows what facebook plugin/module etc does this. I searched a bit, and this seems to be it.

If anyone has a better idea or an alternative let me know. I really like the fact that once I like a website in general it is able to give me updates on my wall. As if it were a sort of rss

cheers in advanced
