Longtime journo and gay historian Charles Kaiser slaps hack Michael Wolff over Wolff's forthcoming hacky Rupert Murdoch bio, to be based on Wolff's hacky Murdoch profile in Vanity Fair: "Why write a love letter to the world's most amoral publisher at magazine length, when you can do the same thing at book length—and make even more money? After all, as even Wolff had the decency to acknowledge, Rupert has already put one member of the Wolff family on the News Corp. payroll." [Romenesko letters]
