Why is this important? Because in the end it will fail. Facebook is trying to copy one of the most efficent ways to browse content on the internet, Friendfeed. Sorry, which one is more popular? Facebook or Friendfeed? The masses have clearly chosen Facebook, and it's quite difficult to switch social networks. Even if UI-to-UI Friendfeed is superior, that doesn't mean Facebook will fail. I'd say that this is a failure on Friendfeed's part, if anything, to turn its superior UI into increased usage quickly enough.
