I was thrilled but also terrified to be invited to speak in the book critic slot on Jesse Mulligan's programme on Radio NZ National. It was my first time speaking live on national radio and, although I was horribly nervous, once I got going I relaxed and started enjoying myself. Here I am speaking about copyright in the digital age - one of my hobby horses. Frankly they're lucky to have shut me up after only a quarter of an hour.
