Very cool, if true

I can certainly see the value of the sub-editor part of things -- but then, with luck, people who are serious about their work would pay someone to do that role anyway... I'm not sure what value the publisher adds to the chain though (marketing and a nice cover?).

I quite like the idea of having books recommended to me by a variety of people and being able to take a punt on them because they are $0.99.

I must admit that these days, while I'm not well off, I'm sufficiently well off that I don't try to save money on book purchases... it's a good few hours of my life to read a book so I don't mind a few extra quid if I think it is a better book than the $0.99 or the free book. That said, if the $0.99 book is just as good and can be reliably recommended...
