I appreciate the complement Nightfall, but Robin Laws is simply genius. Not only is he one of the nicest, most professional designers I've ever had the pleasure of working with, he's also incredibly talented, inspired, and brilliant. Robin Laws is one of the greats and I am humbled to have my name next to his.
Another thing to remember is that although Robin and I were the design team on this sourcebook, it did undergo changes in development to match the vision of the development team. In many ways, it's as much the book of Mike Mearls, Jesse Decker, and Steven Schubert as it is ours. They too did great work on this sourcebook to make certain that the final product fit with the D&D Hell, while reining my darker impulses when working on evil material (see various entries in Book of Fiends for examples).
And Psion, thanks, that makes up for the fact that the blame for "lowest common denominator" falls upon my and my fellow freelancers' shoulders. (Jeez. Sorry for kicking your dog, man.)
