Yes and to be clear, one uses "TFA" to imply annoyance that TFA hasn't been read.

e.g. "TFA covers this already."

That’s not something I wanted to imply. It can also stand for "the fine article". Is there a better shorthand for "the article linked at top of the page" / "the original article"?

And for clarity to @lukasgelbmann - I answered the questioner that clearly didn't know the term. I wasn't referring to your usage of it.

Context and tone tell the reader whether it's used "normally", tongue-in-cheek, or neutrally. ~\_O_/~

To ESL folk out there - the "F" definitely never means "fine". It's a cute and crass ... just like America. ;^)

TFA works fine either way. It's OK that it is subject to interpretation.

Nope, one simply says "the article".
