Hehe, this is getting ridiculous...Wasn't friendfeed.com created before facebook? Even if it wasn't (or was) there is no way this could hold up.

  I'm pretty sure Facebook bought friendfeed. I'm not sure exactly how patents work, but it seems this would mean you couldn't cite friendfeed as prior art.

    Don't worry, the USPTO doesn't know how patents work either.

    If a technique was publicly known, it counts as prior art.
