As reported in Publishers Lunch, Mad Max Perkins will be moving on from blogging:

I'm off to work the program, the 12 steps of Narcissists Anonymous. And to apply myself, whole-cloth, to the business of being an editor. I'm not quitting a sinking ship; I'm just stepping down from the quarter deck (I was never officer material in the first place), and resuming my duties as deck-swabber first class. I return--refreshed and rejuvenated--to "fighting my corner" in the way that suits me best: one book, one author, at a time.
