Thoughtful response, NuggetHoarder.

Funny that "rapid fire" email seemed too slow when instant messaging became popular, then SMS on our mobile phones broke our tether to the computer. And then a further generation does most of its text communications through social media (Facebook, Twitter, etc.) The technology is giving us new options at lightning speed, but social behavior hasn't really been able to keep up with it--at least in developing conventions beyond the merely casual level.

I agree that training would help with whatever communications methods a company decides to use, but how many companies train anyone anymore? Nowadays, employers seem to expect new hires to either already have all the skills they need or it's all on-the-job "training". And forget about ongoing training for existing employees.
