Off-topic on my part here but I think it is so weird that people say “TFA” when referring to the article in the way you are doing. I see this a lot on HN.
IMO it would be natural to use “TFA” in the same way you would use “RTFM” — when you are scolding someone for not having read what they should — but using “TFA” as just a synonym for “the article”... that always throws me off.
