There are a few guys I regard as both knowledgeable and friendly toward Fujifilm gear. Theora Apophosis, Omar Gonzales, Bigheadtaco, Three Blindmen and an Elephant, and the Fuji Guys all come to mind. Of those, Ken Wheeler (Theora Apophosis) stands out for me with his technical acumen, and he has even written an ebook on Fujifilm gear. He is not palatable to everyone, as he is very blunt, and not apologetic for it.
