I'm no expert in business or high tech but these recent defections by best-selling authors, starting, I think, with business author Steven Covey and now including novelist Ian McEwan and perhaps soon Anne Rice (who I saw on an Amazon thread recently asking readers what they would think if she bypassed her publisher and inked a deal with Amazon) seem to me like foundational cracks to the infrastructure of existing publishing. (The chairman of the Society of Authors is quoted here as thinking much the same thing.)
