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.
