Like using that /s or using that smiling emoji sign you used.
A good joke would land even if some other people miss it because of the text format.
"Microsoft would never do this" would have landed for me.
/s is basically the internet-enabled equivalent of a sarcasm tone or a wink - it is much more difficult to detect genuine subtle sarcasm on the internet because of the absence of common communication tools. /s is also a valuable accessibility tool for those that might have difficulty with social cues and subtlety so, for all my autistic friends, I'm happy to defend it.
If you can tell sarcasm from text, that doesn't mean everyone can.
For my part, the smiley face was much-appreciated as I've seen people who genuinely would think that with a straight face.
