It looks like facebook is engaged in a race to the bottom, against it’s own metrics. The easiest way to be engaged is to repost memes and fake news shock posts, so the most engaged users are meme posters and fake news trolls, so features that cater to meme posting and trolling get the most bang for buck, so they’re getting trapped in a cycle of circulating ever increasing torrents of drivel.

My girls are 14 and 15 in the UK. None of their friends use facebook, and that’s not just their social circle. Facebook is just not a thing for them. The only reason they use it at all is because there is one out of school club that posts their upcoming activities on a FB page, so they literally log in once a week to check that page and they’re done. They do heavily use Instagram and WhatsApp though, so they’re not entirely out of the FB sphere.
