outdoor, travel
Maybe let’s introduce them to Wanderer first?
Productivity
I doubt they would remain here. The Threadiverse is biased towards Open Source and ethical solutions and for any normie not interested in it at all this will bore them quickly…
all about pets, dogs bunnies cats etc
A traditional forum is better for that purpose. One would better build it on NodeBB ;)
european tech workers?
Why would they use specifically the Threadiverse, if they could network better on (larger) Mastodon?
movies, animated movies, series, animated series
There was lemmy.film, but it went belly up. Many of communities from there moved to lemm.ee and then to PieFed.social.
And there is https://adultswim.fan/ .
anime, manga, manwha, webtoon
We literally have got https://ani.social/ .
gaming
https://lemmy.zip/ is skewed towards tech, PCs and gaming
instance for every city? mabe for every region?
It worked for much of Europe, for Canada, Chile, Brazil and Oceania. Regional instances were attempted for US and apart from https://midwest.social/ and https://yall.theatl.social/ (related to Mastodon instance) they failed.
European Union hub
Main problem of Europe Pub is that it isn’t a PieFed instance. Topics would easily direct interested users into their national subs, which already exist on national instances. Nowadays it is a duplication of effort, which either fragments or needlessly centralises the European Threadiverse, depending on its success.
medical advice
IMHO Quora would be a better place for this than Reddit (shall it not enshittify)
Of course we can create another large set of sublemmies for new people to think that they may post there, but then it becomes apparent, why Ernest from /kbin has named them Magazines, and not Communities…
I will spare you guessing: with so much “community” names and few people using them “comms” become just categories to post and follow. It may work for a social news website (as it was a primary format of Digg and then Reddit), but this will not replace Reddit as place for discussions.
