Is this sarcasm?

[dicomdan]

Yes

[jacquesm]

Suggest adding a /s in the future to avoid confusion.

[jazzyjackson]

the goal is communication is not always clarity

the fun of sarcasm is knowing enough to recognize it

if somebody is too out of the loop to recognize it and picks an argument, it's collateral damage

[jacquesm]

That may be so, but in normal communications, such as speech it is tone of voice and possibly non-verbal hints that will indicate sarcasm. Online you don't have that and the 'collateral damage' can result in a lot of wasted bits from people reacting to the words rather than to the joke and this in turn can drown out the rest of the discussion.

Adding a /s to a post is the internet equivalent of saying "just joking haha" after saying a joke. It ruins half of the fun.

Sarcasm doesn't exist on the internet until you add a slash s.

Slash s.
