It turns out, Facebook is insanely useful for keeping in touch with friends and family, and for organizing events. It simply doesn't have any competition for those use cases.
And there's no pressure to constantly post updates like there is with Instagram or TikTok, so even the kids and teens are getting into Facebook (albeit highly curated because their parents/family can see the posts). Tiktok/IG are still where they post silly shit and memes for their peers, but FB has become the place where they post the stuff they actually care about.
If your friends are the type of people who just post troll posts, that says more about your friends than it does about Facebook.
Maybe it's how they use the platform which seems to work more better.
In some countries the only place a business exists online is on Facebook (or lately Instagram).
Maybe it's going to be like KFC where it's well alive and lively in countries outside of the US.
Since withdrawing from FB and nearly all major social media, my in-person meetups are far more fulfilling.
I'll just miss the ambient information about my friends.
