Maybe I live in a bubble, but I just assumed that Facebook would be on a decline trajectory by now. Their website is almost meaningless to my day-to-day life at this point. I login once every couple of weeks, upload some pics of my kids for Grandma to look at, and then log off. I don't personally know anyone who still uses it regularly as we did back in 2007. I don't know a tactful way to put this... but it seems lik…
First of, messenger is my most common form of communication with friends and family. I use both the messenger app and messenger.com
The next biggest concrete use is event planning. Pretty much all my friends use facebook events to plan their events so I get invited to the event on facebook. I probably wouldn't not get invited otherwise. That's not because my friends aren't thoughtful, rather it's because it's the path of least resistance. Create an event, look at your friend list, add everyone you hope will come, done. Also if it's an open event it makes it easier for friends to add friends.
I also found out about tons of activities. If a friend is going to or has shown interest in an event facebook will often show that to me so I found out about several activities I wouldn't have attended otherwise.
Friends also directly accounts events they're promoting so I find out about those. A simple example, the Tokyo Indies (indie gamedev) meetup is announced on facebook (among other places but I don't use those other places)
Then, even if I were to ignore all my friends my mother and my sister post semi-regular updates.
A few things that help though
1. I've aggressively unfollowed tons of people. Anyone I don't really care about. Anyone I probably won't see again in my life. Anyone who posts too much (except my sister). Anyone who posts too much political stuff (just don't want to frustration). Anyone who used to be kind of part of life but no longer really is.
2. If FB shows me something I don't want to see I always tell it "hide post", "show me less of this". Their algos suck unfortunately but it helps a little
3. I'm running FBPurity to filter out lots of inane posts. Any "so-and-so commented on" or "so-and-so replied to a post" or "so-and-so was mentioned in a comment" and lots of others.
I will say the more FB tries to tempt me to interact the more I think I'll eventually have to quit. The latest is the popups for comments. I get that it would be useful for people but it's just such a distraction for me I want it off.
