And nice means "mean or small-minded", and silly means "saintly", and terrible means "inspiring terror". Or at least they used to -- but usage evolves over time past etymological roots.

"TFA" is indeed a back-formation from "RTFA", which is the online-forum equivalent of the aggressive and obnoxious acronym "RTFM". But it contains no verb; and in online discussions there's a sort of a hole in our language for an efficient way to say for "the article currently under discussion". So it quickly lost the aggressive and obnoxious connotations that RFTA has.

As such, I think "The Fine Article" is an expansion more fitting with its evolved usage.

Although that's what I originally learned it to mean -- from a horribly toxic online space -- some people use TFA to mean "The Featured Article" aka "the article under discussion."
