Mentioned yesterday in the section about books coming out next Tuesday, September 2, Bill Tancer, author of Click: What Millions of People Are Doing Online and Why it Matters, is general manager of global research at Hitwise, not, um, Hitline. As eagle-eyed Howard Cohen of Keen Communications/Clerisy Press, noted: "When I was growing up, Hitline was what you called to request bad '70s pop music on WPEZ Pittsburgh. I hope he wasn't responsible for that, too."
