Lemmy users are reporting widespread confusion and bugs with the language settings, leading to content visibility issues and errors. The system's behavior, such as hiding content when 'Undetermined' is deselected, has caused significant frustration.

Users like 'madeindex' and 'WhoIzDisIz' describe the language system as confusing and buggy, with 'madeindex' noting that setting the language to English results in missing comments and replies. 'SnotFlickerman' argues that most posts are undetermined due to lack of language selection, while 'Apytele' suggests the backend should prompt users to select a default language on signup. 'Holytimes' calls the system 'a STUPID ass system', highlighting the intense frustration with its design.

The community consensus is that the language system is poorly implemented and confusing, with many users advocating for a more intuitive or flexible approach. While some argue the feature is largely unused, others emphasize the need for a better user experience. The debate underscores a clear divide between those who see the system as ineffective and those who believe it should be reworked for clarity and usability.
