My FB feed is essentially zero content (500+ friends mostly over 25). It’s an aggregator nowadays of group discussions and primarily page content, even pages I don’t follow. Nobody but boomers use it to share nowadays.
I haven’t been on Facebook for a few years, but I saw the same the last year I was on the site. I had unfollowed everything, except friends. You could go through my entire feed in 3 minutes once a week.
Almost nobody was posting anything, mostly it was shared posts. If it wasn’t for Facebook killing forum and small websites, more people would have left years ago.
