Workslop and who pays for it
Generated text takes seconds to send and minutes to read. I suspect the norm gets set by whoever has the most authority in the thread.
This is a short post. By design.
Generated text takes a few seconds to send. Several minutes to read. For one person to save a minute. For three people to lose five minutes each. It seems like a weird bargain with people you like to work with.
The team all mimics whoever is the most senior in the thread. If the manager sends a weekly email with four paragraphs pasted in the body of the email, that is the new definition of update. I had a longer version of this written up. A bunch of fluff.
