I ruthlessly unfollow people who post garbage links on FB and only follow who post their own content so I find my FB feed to be surprisingly sane and helps me keep in touch with people I've met throughout the years in all the cities I've ever lived in, which is not a few.
Despite younger people and curmudgeons retreating from FB -- no concern of mine since my own social network of people my age is what I care about (and one day soon the IG and TikTok crowd will learn that they are old school grandpas too and that they're the MySpace of their generation) -- I find I can still tell stories with pictures and words on FB better than any other platform except blogs, but no one follows blogs these days. IG stories are too short, posts are too limited (you can't caption individual pictures), and TikTok requires you to sit through a 15s video.
Because I ruthlessly unfollow garbage, I don't think I've seen a political post or any divisive content in years. Instead I've gotten to "travel" with friends to different countries, gotten updates on their kids and their struggles with growing older, volunteer efforts that they're part of, etc.
FB is still useful for those of us who use it correctly, and for those of us for whom the written word is still more important the pictures or videos.
