Hi Petal - glad you enjoyed it - I've been watching it as a recording and am only partway through but like you, I was surprised and impressed by the attitude of the Random House rep (and baffled by the whole book-sniffing thing!).
One interesting thing that came up was the existence of the Institute for the Future of the Book, "a think and do tank exploring the future of the book". Here's a link to the
UK branch.
