Well, I did write an entire additional thread.
Explaining a joke is like dissecting a frog. You understand it better but the frog dies in the process. 1. Introduction- What Does "No One Reads the DMG" Actually Mean? So my undying love of Leonard Nimoy, long-running jokes, and the many nifty and obscure things tucked away in the 5e DMG led...

I think that this debate is fundamentally a category error. People that keep saying that the DMG must include a chapter (or whatever) instructing new DMs who have never DM'd before ... are (IMO) missing the purpose of the DMG. It's a reference guide for DMs, not a "learning how to DM manual."
The links I provided make that explicitly clear. The best way to learn to DM is to combine instruction with practice. So the website has a tutorial along with a sample encounter. And then it provides additional instruction along with showing that the preferred starting point if you're new to DMing is ...
A STARTER SET. It's in the name!

I think reorganization of the DMG (esp. wrt a better index) would be great! I also think that they could re-visit the material they include and remove based upon the experiences of tables. But the demand that the DMG be used for onboarding brand new DMs is ... IMO, misplaced. That's not the purpose of the book, and (TBH) reading a chapter is not a very good way to learn to DM. The best way is to do it- as in running a starter set adventure.
