I've reconnected with many childhood and high school friends. And we mostly post stories about pet sitting and dog walking. I've fine-tuned my friends list to be very non-confrontational and benign.
^This.
Whenever someone complains about social media, my first thought is "It is what you make it" or more specifically "All of the content is based on who you follow, don't like what you see? find new friends".
I joined MySpace and Facebook back in the day for the same reason - to maintain my band's presence online.
Back in the day I used Facebook to reconnect with old friends and stay in touch with distant family. When my son won an award or graduated jr high/high school, I didn't have to email and call and send postcards, I just posted a few pix online (not 72 pix like some people, but that's a whole nuther story) and everyone knew. I posted a class photo of my fifth grade class and everyone was able to tag themselves (including the teacher) except for two "military brats" who came and left quickly. And I used Twitter (pre-X) to see what celebrities and bands I like are up to (and catch cutting edge news stories moments after they happened, that used to be very cool).
Now Facebook is 95% reposts of images that say "I have many moods and they all require chocolate", "{politician} did these 50 things therefore they are working for Satan", "You are strong, you are confident, you aren't crazy but if you are that's ok, you can leap tall buildings in a single bound". In other words, nothing real. And TwiXter is 95% "the current administration blah blah blah and that's why we need to be even more divided".
I could thin out my friend/follow list so it's all pleasant stuff, but I like to keep my ear to the ground in regards the local nutjobs, so I have an idea of when the upcoming wacko revolution is happening and what lies they're justifying it with.
