Do you have any suggestions for GM reform?
The current system is probably the best system that is reasonably possible for the game. GM reform would at best do nothing and at worst harm the Game Engine even further. All current problems with the Game Engine are not structural, but solely relate to the long-term lack of active story writers.
With all due respect, I have seen GMs in the past say the exact same things you have said and then, once in office, go inactive for lengthy periods of time (if not outright resign). I would like to think that these men weren't just bad at their job and that we can do better in the way we structure the GM team.
