I did assume the best—hence pointing out twice how helpful the comment was. I was merely curious why the author of the comment used TFA, and if they meant something else than the typical meaning of the acronym. Unless you personally know the contents of the author’s mind, I don’t believe you can answer for their meaning with much authority. You seem to have misunderstood my intent with asking (or do you generally like reminding long-time HN users about rules?). I’m not offended by the usage of TFA or assuming the worst of the commenter. I am curious about the juxtaposition of a helpful tone alongside a rather well-established acronym. Either way, thanks. I’ll hope the author confirms that was their actual meaning.
