One of my questions: How is UEFI pronounced? was closed because it apparently was primarily opinion based. Know that it had the potential to flagged as such, I specifically worded it to ask for 'most common' if not accepted pronunciations to gather/survey numerical information on what the computer community's take was. For future reference, why was my 'statistics' based question closed?
Who defined what is "most common"? For that you'd have to run surveys with a representative sample of people in a representative sample of countries and then ask them how they would pronounce the four-letter word "UEFI". Anything else would be speculation, or personal taste, but in any case there does not appear to be any ground truth here.
There's a similar question where people just post what they think it right. And another one. Both exhibit the typical problems with these kinds of questions—answers like:
Everyone I know…
Everywhere I have been…
Purely anecdotal, but…
Everyone I know pronounces…
Most people say…
Am I an idiot for saying…
Generally, it's more of a language issue without a definitive answer. Perhaps it could be reworded to explicitly ask whether there is an official pronunciation. That'd be a question that could only have a "yes" answer with a link to a reference (or "no" with a reference). Any other answer would have to be deleted—like they'd do on Skeptics.
