PSA: You should know that Settings > Migrate Subreddits exists. All you do is login to your old Reddit account, copy a “multireddit” link, paste it in Voyager and you’ll be able to search the fediverse for those topics/communities to subscribe to.
You may find communities that are missing here if you’d like to run/manage your very own community on a topic you enjoy.
Hope this helps. I just found this feature today and subscribed to a bunch of communities.
Neat find. Thank you.
Obviously, it can only search one way, so subreddits that are combinations of words only find communities named exactly the same (e.g /r/andor finds !cassianandor@feddit.nl but /r/StarWarsAndor doesn’t, and /r/starwars doesn’t find !star_wars@lemmy.world), but given how many communities are named the same, that’s not much of an issue (and it can always be supplemented by manual searching, of course).
