I mean, you're kind of proving the last point by using an emoji in your own message .

I think punctuation could be over-thought, but the use of new language techniques for conveying tone in written communication is essential these days. Bold / italics / other methods of emphasis and emojis are an integral part of making sure something comes across more or less as intended.

Consider:

"Hahaha, you're funny "

"Hahaha, you're funny "


"Wow, he's really clever!"

"Wow. He's really clever. "
