You're not, we also have English communities like https://feddit.it/c/askitaly And you're free to make post in English in italian communities using the English tag
The only thing they have at registration is that you need to write a sentence in "some regional italian slang" And that's basically serve the purpose to restrict a little bit sign in not to finish like lemmy.world targeting italian speakers
But it's actually pretty easy
Indeed I can understand this one. I'm really liking Lemmy but discoverability is pretty bad, add the fact the ranking is shit and pretty useless in suggesting interesting content and you will understand his point.
Reddit has both much more content and not only a better ranking system but also a functioning personalized algorithm, if you want to use it.
To this day, all of the non mainstream Lemmy communities I'm following it's because I've used to follow the subreddit and it migrated here.
