Josh Quittner, the Fortune executive editor who's reportedly plotting his escape from his gilded cage at the magazine, has written a perfunctory profile of TechCrunch blog impresario Michael Arrington. Nothing we haven't read before — including the obligatory paragraph about Arrington's conflicts of interest in writing about startups even as he invests in them. Quittner observes that the practice seems to boost Arrington's reputation in the Valley. One conflict Quittner never mentions: As editor of Business 2.0, where I worked for him, he tried to strike a deal with Arrington to save the magazine by merging it with TechCrunch. The effort failed, landing Quittner at Fortune.
