This is already a thing. If you client doesn’t have the language setting for your profile, you can do it on the web. Log in to your instance from the browser, navigate to your profile and choose your languages. After that you’ll stop seeing the majority of posts in other languages.

One real-life community may need several Lemmy communities as per each topic.

Care to share? Thanks!
