Contents are not powered by algorithms. They literally show stuff from people you follow. My timeline has most posts in English about Bitcoin, some posts in Portuguese from Brazilians, and sometimes Turkish, Italian and Russian from Bitcoin people that decided to interact with their fellow countrymen. I just skip these weird languages. Twitter does nothing to prevent me from seeing them.

Yes you are right, the Twitter style is centered on the followed people.
But Nostr could be have other use case, right? :)
Think about a Nostr Medium replacement with long content, I would like to discover independent journalists without searches on random arguments, how can I achieve that without a lang filter?
this is a good point
it doesn't prevent it from your follows. it does prevent it from the twitter general content it seems. like if you sign up for new account and have no follows you will only see your own language.
I guess i think its higher signal if you can filter which language you see from your follows (especially if you normally skip those weird languages)
It may be time to warm up Duolingo on those languages... Or warm up AI translator :)
