A rather good piece by Mike Shatzkin on Seth’s move.

Publishers should have remembered the axiom that you should be careful what you wish for. This was, perhaps, the beginning of the unbundling of the publisher’s suite of services to the author. It used to be that the publication of a book was the platform and the publishers’ publicity and marketing efforts worked to capitalize on it. This was all part and parcel of the package: paying an advance; editing and shaping the book; putting it into a distributable (printed and bound) form; getting it known; and, of course, getting it into a store where a customer could buy it.
