When confusion gets framed as "this is substandard writing", it rewards showing up and performing a lack of context rather than engaging with the substance or asking clarifying questions. Over time that creates pressure to write to the lowest common denominator, instead of the audience the author is clearly aiming at. ... So yeah, I am genuinely curious why you see personal unfamiliarity as something the entire discussion should reorganize itself around.

(Shrug) The fact is that all major style guides -- APA, MLA, AP, Chicago, probably some others -- call for potentially-unfamiliar acronyms to be defined on first use, and it's common enough to do so. For some reason, though, essentially nobody who writes about this particular topic agrees with that.

Which is cool -- it's not my field, so I don't really GAF. I'm mostly just remarking on how unusually difficult it was to drill down on this particular term. I'll avoid derailing the topic further than I already have.
