When you do interviews, do you typically ask closed- or open-ended questions? If you don't know what I'm talking about, trot on over to this great story about interviewing guru John Sawatsky. The story talks about how conventional interviewing techniques often don't work.
It includes some interesting anecdotes about well-known TV journalists falling flat in their interviews, generally because of closed-ended questions (ones that can be answered with a "yes" or "no"), rather than "what," "how" and "why." Seeing Sawatsky speak at a workshop a few years ago had a big influence on me. If you don't have a chance to see him yourself, check out one of his books.
