">In other words, people will decide what news site is more respectable than others, not Facebook's algorithms.<"

Well, we will see about that. I call this PR stun. How long will it take, before their algorithms start clicking on likes like they would be coming from users? They are already censuring. fb is, just like google, very politically biased.
What are the chances, that some news will rank high, if news is opposite what fb's political stance is? Not a chance, media is there to mold users opinion as media wish, not to report the facts.
