As a human, can you please tell all of us what these abbreviations are?!
...TFA: The Featured Article
a.k.a. (also known as) OP (original post(er))
This is one “human corner case” I have no shame working around. Wouldn’t want to convey hostility where none exists.
I prefer "TFA" to "OP" as the latter may be ambiguous as to whether it refers to the article or, more typically in my experience, commentary on it. Even here, "OP" might reference either a thread root or the parent of the post immediately being replied to.
In the second case, if I were to say "OP" here, I'd be referring to your comments parent, by tchalla, https://news.ycombinator.com/item?id=30345056
It refers specifically to the submitted article, and carries an overtone, sometimes tongue-in-cheek, sometimes subtle, sometimes more blunt, that the person being referred to ought to read the specific submitted work more closely. Perhaps at all. And without crossing HN's guidelines against specific accusations.
That is, the meanings are similar but different. "TFA" is more concise and specific. All of which make it the more fabulous ;-)
It turns out I do use both terms fairly frequently, as my comment history shows. The distinction is largely as I've described above. "The article" usually refers to some additional or other reference rather than the HN submission. "TFA" in the context if "you/I should have read that closely".
