That's true, the singularity in some way could occur. Do we not also choose who we are friends with on Facebook? We don't necessarily choose 100% of what we see from them, but on Facebook we also retain the ability to seek that information out. I want to know how a friend is doing? I go to their page, I don't rely on the news feed. The newsfeed operates as an unknown unknown - if you are not a conscious user. However, as I said, it's not like the newsfeed is the only way to get content. In addition, anyone who goes to a user's page in order to see what's up with them, and then revisits the general news feed, should be able to notice that not everything posted on the user's page appears in the feed. I do not think it is as mystical as you are presenting it. Maybe I am overassuming average intelligence, but I think after looking at one or two of your friends' pages on Facebook and navigating back to the feed you'd be able to realize that clearly, not everything is making it across.
