On BloggingHeadsTV, Jim Holt gives a textbook example. As the interviewer, you're supposed to be the showcase, not the show. Holt asks rambling questions, monopolizes the conversation, and steals the author's thunder.
To see author interviews done right, watch anything done by Brian Lamb on C-Span's BookNotes. Or listen to the Glenn & Helen Show.
By the way, the book is Traffic: Why We Drive the Way We Do (and What It Says About Us). The author is Tom Vanderbilt. Hard to tell from the interview, but I'm guessing it's very good.
As for BloggingHeadsTV, check it out. My favorite regulars are Mickey Kaus!/Robert Wright, and John McWhorter/Glenn Loury.
