JOHN SCALZI IS unhappy with Amazon over the Macmillan dispute. “Hey, you want to know how to piss off an author? It’s easy: Keep people from buying their books. You want to know how to really piss them off? Keep people from buying their books for reasons that have nothing to do with them. And you know how to make them absolutely incandescent with rage? Keep people from buying their books for reasons that have nothing to do with them, and keep it a surprise until it happens.” I like Amazon, but this seems to have been poorly thought out.
