Hamishcampbell, (edited ) They all share #4opens #openweb tech, so this is a win.
Where they differ is in the "culture" they come from and push.
#bluesky comes from surveillance capitalism, it's from the #dotcons and has meany of the same assumptions, just "better".
#Nostr comes from the #encryptionists and #bitcoin bro crew and suffers from being from this mess.
#activertypub is #openweb native and comes from the #4opens traditions the whole software world is actually built on.
