Unrepentant DM Supremacist
I'm not convinced by the argument that new DMs benefit from more hand-holding or systems to make it easier for them to run games well since, well, being a DM isn't exactly rocket science! Tens of thousands of people were running fun games of D&D back in the 70's and early 80's with what little support and advice was available back then.
I don't think new DMs need their hands held, but I believe they do benefit from having the learning curve eased a bit. We all know it's higher for them than for someone running a PC simply because they have more to do and more they need to keep track of.
