I remember when you could go on Facebook and look through your feed at what your friends are saying, catch up with them, and browse posts that they have made. Now, it's just completely random and chaotic, almost nonsensical. There's no logical sense to my Facebook feed at all. As you can see in the image, they are showing me stuff that I'm not even following. This is not even something that I am actively a part of! It's some random group. So what's the point of following a group or liking a page, if they're just going to show you random stuff anyway?
