So, like, just how much is Facebook manipulating and tailoring what I see already?  I&#x27;m already fairly certain it&#x27;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 &quot;like&quot; 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, &quot;don&#x27;t show me stuff like this.&quot;  It sounds like this is a start to exposing that functionality.  Are they very slowly and gently admitting that they do manipulate our feeds?
