And yet Facebook has 3 billion monthly active users: https://www.demandsage.com/facebook-statistics/
Eventually I logged on and noticed that as I was scrolling, like 2/3rds of the content wasn't from my friends at all, not even re-shared stuff, it was all ads or shorts from randos or random group pages that somehow appeared on my feed. And of course a lot of the things from my friends were, in fact, re-shares.
I felt like, if only like 20% or less of the content is original stuff from my friends, what's the point of even being here? This is terrible. So I gave up.
I entirely agree with you.
