I'm getting all my friends into Meshtastic, a system of mesh networked packet radios that can be very cheap and do not require a HAM license.
A few of us will be trying out then forking a BBS running on an RPi connected to a radio node. Though that will technically be less decentralized, it will be more social media like.
Matrix has at least 3 times as many users as bluesky. And most servers arent even publishing their users counts. But arguably most people arent using matrix as a social media platform. I wouldnt count discord as traditional social media either.
This is real, btw.

You are ridiculous, and I love that for you.
