Just commit, no matter the response. Adding /s is akin to explaining a joke after you tell it. If someone doesn’t understand or pick up on the sarcasm, it’s not your responsibility to spell it out for them. You add /s because you don’t want to be held accountable.
Thanks, appreciate it. Smart move not using it in person with people you don’t know. Online, it depends on the situation for me. Most of the time I find that the context the comments are in will pick it up. However, there are some comment chains that I add an /s just to make sure it’s clear, or if I’m changing context from a sarcastic tone to a non-sarcastic tone.
Reddit was and Lemmy is pretty good about it. If I’m ever on corpo-social-media, which, not really anymore, I never use sarcasm. Even if I said it’s sarcasm someone will still jump down thinking I’m being serious.
