This is one of my constant frustrations on Lemmy too. People constantly dropping abbreviations with no explanation, assuming their cultural background is universal.
Yeah, I can remember them from the early YouTube days, but I wasn't 100% certain if it had been decades yet >!and I didn't want to think about how old I'm getting!<
I don't know if I've ever heard the initialism AMV or not (though I've watched plenty of them), but even not knowing what it was it was pretty easy to figure out from context (though i thought "animated" instead of "anime", but close enough anyway)
Some acronyms and initialisms, I don't really get why they're so hard for people, especially in context
It is wild that this post about a harmless abbreviation that refers to cringey (but endearing to me) narrow slice of early-mid 2000s internet culture got this reaction out of you. Something that could be ignored or looked up.
Be it Lemmy or the communities you stumble upon, but perhaps some introspection about how you respond and interact with the internet could use a revisit.
All of those but AMV are really common. Amv is not. IKR might not be that common but I knew it. In any case, all of those are sentence abbreviation but amv is a noun, its different.
My point wasn't about how common they were, it was about how easy it is to find out what they mean. I don't think it matters whether we're shortening a common phrase or a noun, any search engine will tell you that AMV stands for anime (or animated) music video. Contrast that with something like MIL, which you can't easily search up (it usually stands for mother-in-law)
My point is that I shouldn't be expected to use a search engine to understand terms of a post in a generically themed community, it costs nothing for the user to put the definition. How common the term is IS something to consider when deciding to put the definition or not. Considering that the most up voted and commented comment is about the term not being recognised, I'd say that my point stands.
MIL should have the same thing unless it's being used in a thematic community like relationship advice. It's common practice for a document that has shortened terms to have parenthesis with the full definition the first time they are used, and in a post thstbwould be the title or the body of the post.
