Not just that, but he's also got this weird idea that the feed algorithm understands people.
Mine right now is:
1. Friend
2. Ad: Mothers day promotion — mine died years ago
3. People you may know
4. Someone commenting on a post shared by a friend, but FB didn't expand the post so I could actually read the comment, this was just an announcement that such a comment exists
5. Friend
6. Ad: jewellery
7. One of my own posts
8. "Are you interested in this post?"
9. One of my own posts
10. People you may know
11. The same people in #2 with a different picture for the same deal
And this is relatively competent! Usually it's just an endless stream of recommendations for things I have no interest in — meme groups, or support a team I've never heard of in a sport I don't follow in a state I've not visited in a country I was last in before the pandemic, or services I can only buy if I was both a citizen of a different country and living in an additional different country, or both (but as separate ads) dick pills and boob surgery.
I may not be interested in the mother's day promo or the jewellery, but I could at least theoretically buy them if I was.
But then I refresh it, and the friend's posts are reminders to vote… in the UK local elections… which were last week… and I live in Berlin.
On the plus side, this makes it very easy for me at least to not find it at all addictive. If only everyone was so lucky…
