I haven't been on FB itself in close to a decade. I understand that it's still somewhat usable for neighborhoods and for keeping up with family, but I don't have firsthand knowledge. Even before I left, getting through the algorithm to see a feed of real people was almost impossible. That's certainly the case on Instagram, which I do still visit a few times a year.
I've never been especially interested in normies, but you may be right. All the communities that I care about are in the fediverse. Any entity that still relies solely on Xitter is a lost cause as far as I'm concerned.
