I've also observed the third direction, which is the message storm.
That's when someone breaks down their point into multiple separate messages, one sentence at a time, when a single coherent paragraph or two would have worked. Why send one message when you can send 7 in rapid succession?
It's arguably the most annoying method of communication because it spams your notifications and you have no idea when someone has finished dumping.
Dumping every sentence saves up tokens in human mind ;-)
Also, any metric ceases to be a good metric the moment it becomes a goal.
I have observed both of the above statements in many different contexts, they seem to be (somewhat) universal rules for human society.
