I used to count how many non-friend items there were between friend posts. If I recall correctly, my max count was 20. And similarly to you, when I do see something it's from 3 days ago and feels no relevant to comment or interact with. I know so many people hate Facebook, but I used to really enjoy those small moments with friends where we could interact over small life updates and photos. Now they feed me garbage to groups I've never subscribed to based on some "guess" around my interests.

I've also done this and my record count was 120. 120 sponsored or suggested posts about things I don't care about in between the posts from people I'm actually interested in.

I'll echo what others have said - if social media is dead, it's because they killed it themselves.

Fun game. I just had 7, then 3, then I gave up after 30. And those 2 friend “posts” were 1. someone sharing a page’s post, and 2. a friend posting what appears to be an automated happy birthday on someone else’s wall. I did not see any actual content from friends at all.

Most stuff on FB seems to be 1. pages I don’t follow 2. ads 3. posts from groups I no longer care about 4. random people who are not my friends but somehow I still get to see their posts in my feed (not even popular posts) 5. sometimes, some uninteresting activity by an actual friend (commented on something, shared something) 6. occasionally a friend’s IG story pops up (I guess these are automatically cross-posted to FB or something)
