Rodney tweeted some additional info with regard to the length of the notes he posted (I combined the tweets):
"Heh. Seeing some folks comment on the volume of material in my session prep notes. It's important to keep in mind that my session notes are an amalgamation of material I prepped for an entire adventure, stuff I prepped specifically for this session, and stuff that sits in a larger general file about my campaign as a whole. For example, the character traits of the NPCs, many of those are from a larger campaign notes file. For the session I ran with those notes, I probably only prepped about a page of it specifically for that session. And the more published adventure-like approach to my notes is something I do to burn the info into my memory. If I write it, I remember it. Plus, this was for a very intrigue-heavy adventure. For a dungeon, I'd probably write much less--room name, contents, & something memorable."
