Update: The page appears to have been removed. This may just be a feature that Facebook is testing. We'll update when we learn more.
Original Article: Facebook has launched a new feature for content discovery. If you go to facebook.com/pages/browser.php, you can "discover Facebook's popular pages".
Users can browse popular pages by categories like musicians, sports, celebrities, movies, TV shows, media, politicians, brands, and games. If you browse "all", however, the results appear to be more personalized, including things your friends like or things that you are somehow connected to.
Users can mouse over any of the images for the results, and like the corresponding pages.
The feature could go a long way in encouraging more likes for pages, and that could be crucial to Facebook as a search tool, considering other features the company has been testing.
Be careful when browsing the new page, because if you click on any of the results, you automatically "like" them.
The page also shows you which of your friends are most "similar to you". It displays how many mutual likes your top frinds have.
