join-lemmy.org shows a few instances at the top of its join page:

lemmy.fmhy.ml (which is based)

sh.itjust.works which im pretty sure is having a free speech or too much user choice problem atm

lemm.ee, a general instance

sopuli.xyz, which i know nothing about (who is finn???)

i dont see .world until a further scroll down from those. did they change it?
