Pogue goes into detail about some personal history he has with Hipmunk co-founder, Adam Goldstein:

Eventually, I hired him as a tech reviewer for "Mac OS X: The Missing Manual," and he was amazing. His writing sounded exactly like mine. I started assigning him little sidebars and appendixes to write. By a year later, he’d written a Missing Manual himself: "AppleScript: The Missing Manual," published when he was 16, too young to sign his own book contract.
