My friends are lovely people and I enjoy seeing their holidays, nights out, dinners and runs. Unfortunately since before Christmas, an algorithm change means I rarely see any of that. I used to use it a lot myself so I can filter fairly easily, and mute the odd Farage-loving grandfather of my acquaintance. I also used to post a lot of statuses until DS was a year or so old - about 2014.
These days I find the focus on news, external content and advertising too much. I don't see personal posts from my FB friends if they haven't got content attached, and it makes me less likely to post anything. I feel like my friends have left and I have got news pages and Hurrah for Gin instead, which isn't what I came for. I counted recently and every third post is promoted content, the top posts are usually the same thing for a week and other stuff isn't getting seen.
These days I open it to scan the memories section for anything embarrassing from years ago (vaguebooking, TMI posts, cringey stuff) and delete it as I'm very aware I'm not just connected to my closest friends and family anymore, but work contacts too.
And yy to whoever said that about posts disappearing. I like to look at some news articles on there because I like to check the comments, but when the news feed refreshes I have no hope of finding it again. I also have to search a friends name and a word they used if I want to see their post again.
I used to use it for news around the time of the referendum but I noticed very quickly that all the news I was seeing was articles that reflected my own view point and opinion. I was trapped in an echo chamber and it was frustrating. I now use twitter which is better for news - not only do people I follow share articles they like but they rebut articles they don't like. I use Snapchat for family where my siblings share pictures of their meals, nights out and runs. I've never liked messenger or how much data it uses us, and I already have WhatsApp which is the same but better imo.
Facebook is the last refuge of a few old friends who live across the world though. I'm planning to delete it soon, but for now I need to use it to get those friends to stay in touch.
