You think facebook is dying? their monthly active users have grown year over year every year so far. It slowed down approaching 3 billion but still grows. https://www.statista.com/statistics/264810/number-of-monthly-active-facebook-users-worldwide/

Twitter's user count by comparison is a joke, 368m in 2022, but as of current statistics they have only ever grown despite doom and gloom over the changes. I always hated twitter, but the facts are what they are. They do predict a decline of the platform but it's far from an abandonment. Since twitter is now private it's unlikely we'll get great data from them moving forward. https://www.statista.com/statistics/303681/twitter-users-worldwide/

Reddit doesn't have equivalency statistics since it's always been private. Best I can find places it somewhere between 800m and 1.6 billion monthly active users. Way bigger than twitter and honestly given that lemmy has yet to break 0.01 billion MAU i'm not convinced lemmy will succeed or not. I'm obviously here because I want it to, i'm just not drinking anybody's koolaid because I wish things to be a certain way regardless of reality.

I don't think reddit will go anywhere, i'm just not using it anymore.
