Get rich quick by giving your product away. Freeing your books on the web, Doctorow-style, is good for you. If you love something, let it go, and if it doesn’t return, you were never any good to start with and should never pick up a pen again in your life. The World Wide Web: literature’s Simon Cowell.
Thinking about it, giving away free digital copies of books makes a lot more sense that giving away free digital copies of music. Downloading a couple of chapters allows you to see how much you might like an author unknown to you. The point being that most of us who like what we read are then likely to go on and purchase the physical copy of the book, because so few of us have the stamina to read an entire book from a screen. Whereas music downloads, free or paid-for, are conveniently portable and these days more and more preferred to traditional media.
