The german communities didn’t transition quite as well as i hoped, but the like of !deutschland and !dach still see enough engagement to serve their purpose.
So i guess those are my favorites so far. Simply because they already function quite well.
Beyond that i am more of a Star Wars/Lotr guy, but i am warming up more and more towards Star Trek (liked it before aswell, but didn’t dive into it too much). Especially since i enjoy some of the current series (Strange New Worlds and Lower Decks) quite a bit.
