I get that, but as someone who got into D&D ten years ago (and my experience is the only one I can go off of), I
read the DMG back in 2014. Cover to cover. Then I went and searched through the same advice on reddit, and got more actionable advice from the internet (stuff I still use to this day).
Could you make the argument that I wouldn't know what to search for without the DMG? Yeah, probably. It was that or it was watching
Critical Role. Or it was stumbling into problems in my own campaigns.
Maybe there isn't a solution to this problem. Maybe the DMG is doomed to be "baby DM's first book" that gives people a starting point, but is otherwise forgotten about/eclipsed by third party/advice you can find on the internet.
Guilty as charged
