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?
Like, wtf happened to this website?
It is a privacy nightmare. However if you only use it for keeping up with distance friends it is a useful tradeoff. However because they must have so much private information to be useful for that purpose you need to ensure they never have any other purpose. Which is why I won't use marketplace or groups - there are alternatives that don't already have private information.
