I have tried Googling a few keywords without luck, so I thought I'd just throw my question to the board and see if anyone can point me in the right direction.
I was a fairly active D&D 3.X player and DM with pretty decent system mastery throughout the run of that edition, but basically fell completely away from D&D and its immediate derivatives with the release of 4E. In the past three months or so I've fallen pretty heavily into Pathfinder, and while I'm a bit rusty on my 3E knowledge, I'm still able to notice this or that rule that changed between 3.X and Pathfinder, and occasionally see things that I'm either surprised or disappointed didn't change.
So, the question. Does anyone know of a Design Diary or even an interview or extensive board post wherein Jason Bulmahn discusses his reasoning for specific changes made for Pathfinder, or even the decision to not change this or that?
