Punctuation rules seem to be changing. I am fairly certain that this is due, in part, to texting and tweeting, where space or time are limited and "you know what I mean" is approved. I have also read that punctuation affects each line of an ebook and therefore trimming commas is "approved."
Recently I received a sample edit from an editor seeking future work. She deleted hyphens from adjectives where I am pretty sure they are supposed to be used. That's how I learned the rules.
I know language evolves. I have accepted that the comma before "and" in a set of three+ descriptors is optional. Yet there are times when my meaning could be misconstrued if I modernize and do not put in that comma before and.
This is an example from a grammar post by MM Pollard, the queen of English:
"I posted the pictures of the strippers, JFK, and Stalin."
"I posted the pictures of the strippers, JFL and Stalin."
Do you trim punctuation to keep up with "modern" rules?
