In any case, I made the mistake of assuming everyone is currently familiar with the idiom just because it was widespread when I joined HN.
I suppose at one point it'll be a mistake to assume everyone knows what ROTFL or LOL or IMO mean, just because they used to be widespread internet culture at one point.
Also, TFA used singularly is different from just saying "the article", e.g. when you want to imply RTFA. Within your comment you could see the "F" part was quite out of nowhere and can be considered rude.
Not if you see actual usage: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
Context matters, and people here usually interpret it as "The Fine Article", and it was indeed written in that sense. It's supposed to be a shortcut (not rude like RTFM, which does have a meaning of impatience because it's directed at people perceived as too lazy to search the docs).
Anyway, a shortcut that requires this much explanation is a failed shortcut, and I apologize for that. It's sometimes hard for me to realize that what used to be a really common idiom that needed no explanations can quickly become something unfamiliar to new readers. Just in case, I won't use it again.
See usage in HN (yes, the latest ones are mine): https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
Sorry, didn't mean to confuse.
I've seen the idiom so many times here on HN I assumed it was widespread. It means "The Fine Article" (replace Fine with Fucking if feeling impatient).
It comes from the extremely well known idiom RTFM, for Read The Fucking Manual, used in unixy/hacker circles when someone asks for something trivially answerable by simply reading the manual.
I forgot that with new generations of techies, the old idioms become obscure or are replaced by newer idioms!
