Finding your GM-ing style: A flowchart
This is the flowchart I wish somebody had shown me when I was getting into role-playing all those years ago.
I was inspired to make this by re-reading the Forge threads on Bangs, Illusionism, Force, and Murk. If somebody is brand-new to role-playing theory I think these topics are a lot more helpful, in terms of actually finding a style of play that you enjoy, than the whole Creative Agenda G/N/S thing. And yet Bangs/Illusionsim/Force/Murk is buried, hidden away in Forge archive threads and old discussions from 2001/2002, while newbies invariably get sucked into arguing about G/N/S, which half the time turns them away from theory entirely.
