In essence, Facebook has rolled out a more substantial way to find Facebook Pages and view shared likes with your Facebook graph... as compared to the more indirect method I wrote about yesterday.
The main directory is fun because it is highly visual... and effective for page owners because users can like pages through a mouse-over (potentially a big lever):
"Discover Facebook Pages: See something interesting? Roll over the Page and click Like to receive updates in your News Feed."
The far more interesting part is the sidebar: "Friends Similar to You". It features a simple way to view shared likes with your Facebook friends. As I wrote about yesterday, I believe this is the skeleton of something much larger: social search.
Good start. Interesting to see how Facebook chooses to drive traffic to this.
