Goodbye Facebook.
Aside from the fact that this post is mostly pointless, it's also totally misinformed.The OP started off by stating his reasons for dropping FB in this "experiment".. namely losing touch with the people for which he originally signed up under.But he clearly doesn't engage with them if he's not seeing their updates.Your social graph needs fine tuning. It's like any good bayesian filter, it learns over time what interests you. You can of course give it a push in the right direction by putting people in acquaintances, or hiding specific people from your timeline. (People in your acquaintances don't show up as often in your newsfeed).This post just shows that you most likely don't understand the full feature set of Facebook and how to best optimize your social graph (not that this is your fault). Facebook has some of the best machine learning for figuring out what is relevant to me. I'd probably argue that you click on too many memes and don't interact with your friends as much if this is what it is serving you.Don't drop Facebook, just learn how to use it. 
I personally don't use Facebook for interacting with that many friends. I have about 96% of my friends as acquantiances. I have a small set of about 10 people as friends, and I subscribe to about 100~ people. 
My newsfeed is so rich with really good content.
