Matrix magazine, the news magazine of the BSFA has put online an interview with Hal Duncan, author of Vellum.
Matrix is a great magazine, as are its siblings Vector (critical articles and reviews) and Focus (writers magazine) and together make the BSFA subscription totally worthwhile. The latest issue of Vector included a discussion of the Mundane manifesto, including an argument against by Ian McDonald and other articles on previous SF movements and discussions of whether manifestos are a good idea. Great stuff.
