Is generational punctuation still a thing?

Apparently so, though it's continuing to evolve. Reviewing Florence Hazrat's forthcoming book On the Mark: From Periods to Interrobangs, How Punctuation Remade the World, Judith Shulevitz focuses on the current generational and contextual differences in English punctuation (" Punctuation: A generational divide ", The Atlantic 7/14/2026).

There was a flurry of attention to such things a couple of decades ago:

" The new semiotics of punctuation ", 11/7/2012

" Agressive periods and the popularity of lingusitics ", 11/26/2013

" Generational punctuation differences again ", 8/1/2014

" Query: Punctuation in personal digital media ", 2/23/2015

What I've seen about it more recently, or at least noticed, is a bit off to the side:

" Prosodic punctuation ", 12/19/2017

" More on grammar, punctuation, and prosody ", 12/19/2017

" Barstool punctuation ", 4/4/2020

" Cumulative punctuation ", 4/15/2020

" 2020 punctuation/prosody ", 9/19/2020

" Punctuation marks hanging out ", 4/8/2025

" Death by punctuation ", 6/3/2026

I haven't seen any discussions of punctuational innovations in other languages/orthographies, like Chinese or Korean, though this might be because it's not happening?
