From seeing the feeds of a few categories of people near me (some using it semi-professionally, some just personally, some like me that avoid it unless strictly necessary)... it really does seem to be all of them. Absolute garbage is a majority, and they all complain about missing things they actually care about (though to be fair this has been true ever since it left colleges).

Facebook is truly awful to everyone. I can't believe people don't try harder to leave.
