Yeah, it gets ridiculous at times. If you’re in a niche community, you can expect to see some “professional jargon”, but in general communities like asklemmy and nostupidquestions using those types of niche acronyms just don’t make much sense.

If you’re in a car specific community, you can throw your acronyms around, but outside it you shouldn’t expect people to know what a BSM is. Be considerate and call it a blind spot monitor instead.
