Honestly explicit sarcasm indication should just die out entirely. Might as well be writing it longhand as "Just in case you missed it, this is a joke haha." every time you tell a joke.
Exactly right, and what I would add is that this is a Poe's Law thing.
I might even offer a corollary to that law, which is that the more unclear a statement is, the more inscrutable a it's intent, the more likely the original author will insist that it was 'obvious' sarcasm.
Exactly, it is the illusion of transparency. Have someone read something you've written out loud, you'd be surprised how often they use a different tone than you had in mind. Add to that a variety of cultures and backgrounds.
Yes, I read it that way too. Which meant that they were under the impression that it is easy to infer tone, so I replied with a serious explanation why it may not be.
I’m assuming you’re joking, but maybe that’s exactly why we need explicit sarcasm demarcation.
