So, like, just how much is Facebook manipulating and tailoring what I see already? I'm already fairly certain it's not simply showing me everything all of my friends post in the strict time order they post them (like it used to in the old days?).<p>I was starting to wonder the other day if it was like Pandora radio. If I click "like" on something do they show me more posts similar to the one I liked? If so, can I please have a thumbs down button so I can explicitly tell them, "don't show me stuff like this." It sounds like this is a start to exposing that functionality. Are they very slowly and gently admitting that they do manipulate our feeds?
