What are the majority of posts you see on Facebook?

Most people on my facebook seem to be interested in the same thing as me so most of the stuff that shows up on my feed tend to be things I like. It's usually funny pics, memes, and links to articles or quizzes. That kind of thing. I don't have a whole bunch of people in my facebook friends. I'm not one who befriends just anyone on facebook. If they leave post that I don't tolerate then I simply won't befriend them anymore but, so far, no one has really done that.
