Traditional book publishers use techniques perfected a hundred years ago to help authors reach unknown readers, using a stable technology (books) and an antique and expensive distribution system.
The thing is–now I know who my readers are. Adding layers or faux scarcity doesn’t help me or you. As the medium changes, publishers are on the defensive…. I honestly can’t think of a single traditional book publisher who has led the development of a successful marketplace/marketing innovation in the last decade. The question asked by the corporate suits always seems to be, "how is this change in the marketplace going to hurt our core business?" To be succinct: I’m not sure that I serve my audience (you) by worrying about how a new approach is going to help or hurt Barnes & Noble.
