Likebutton.me shows what your Facebook friends like, all over the web
Likebutton.me has columns for a slew of prominent websites, from CNN to YouTube to Break.com. Each column shows things your friends have recently liked on the site, and then a list of the most-shared items from that site. Basically, it's the Facebook zeitgeist in one place, with a bit of personalization. As Facebook gets bigger, a site like Likebutton.me gets closer and closer to giving a complete picture of what's happening on the web.
