I come here for intelligent discussion not useless sarcasm. This is HN right, not Reddit?
That post was sarcasm, but it was incredibly intelligent sarcasm. Irony tends to be one of the higher forms of comedy when well executed.
Prose don't communicate sarcasm easily without explicit notice. Check out The Beggar's Opera (https://en.m.wikipedia.org/wiki/The_Beggar%27s_Opera). It's actually really funny. Reading in college, no idea. Thought it was boring and everyone was bitchy. Seeing it college, lols. It's the play that inspired the play that brought us Mac the Knife and inspired Mac Tonight.
