So Facebook sucks.
I'm sure everyone who uses Facebook realizes that it loves sticking random ads and suggested groups in your feed instead of actual posts and updates from your Facebook friends. I noticed this, naturally, but then I decided to game their algorithm to make it show me posts from groups dedicated to posting pictures that I'd enjoy seeing. (For the sake of discussion, let's say they're "landscape paintings".) Every time a "landscape painting" post showed up, I would tap/click on it so that the algorithm would see that I was interested in stuff like this, and it would therefore show me more "landscape painting" posts in the future. Eventually I got it to the point where I could open up Facebook, see a few updates from my Facebook friends, and then scroll through an endless collection of "landscape paintings" from a wide range of groups, all handily curated and collected for me by the algorithm.
And then apparently something changed in the last couple of days for me, because now I'm only getting Facebook friend updates in my feed, punctuated by unrelated ads. I don't care about my friends, I want "landscape paintings" dammit!
