Facebook just began testing a new feature "happening now" in a sidebar to the right of their news feeds. It's filled with links friends have posted that other friends like.
Similar to a Twitter timeline, the Happening Now sidebar displays additional information that isn’t usually on the main news feed – i.e. friends liking a link or making new friends. The Happening Now sidebar also updates in real time, letting users read updates as soon as they happen without having to click a link to refresh.
It looks a lot like a Twitter feed with a bunch of re-tweets in it. A re-tweet effectively does the same thing as "liking" someone else's link, shared on Facebook: share a link you like with others.
