From what I have seen, HN is not especially keen on sarcasm either. Which I somewhat disagree with, I think it's a good alternative way how to make people think about something, rather than directly attacking the argument.

If ML algos ever manage to recognize sarcasm then we're truly in trouble. Sarcasm doesn't translate well on the Internet, especially for non-native speakers. Tone just doesn't come across well in text.

I have heard (seen) the statement so many times. Personally, I find it quite trivial to detect; so I suppose it's partly related to how much sarcasm one would indulge in normal daily routine.

Gotta train on that dead pan delivery.

Indeed, and to me the sarcasm was beyond obvious - 1st sentence: two words and an exclamation mark. One interesting caveat was that the account was brand new (like just created).
