OK, strictly speaking not just wefwef, but please understand that the languages settings in the web-interface of Lemmy can have huge impact on your experience.

If you choose the wrong or not enough languages, you might miss out on content posted to the fediverse.

Don’t get me wrong, the language setting is a good idea. But it appears many users don’t understand it and post in some language irrespective of the actual language of the OP, resulting in you not seeing those posts.
