ReadWriteWeb has an interesting post about an author, Daniel Oran, who is using Amazon.com's Kindle ebook device and sales platform to fine tune his book before publishing. Oran is allowing Kindle users to download his latest draft of Believe for 99¢. The author is using the Amazon discussion and review areas for readers to provide feedback as the author works to fine tune his book for final publication. After gathering reader feedback, the author plans to publish the book in the traditional method. Proceeds from sales during the beta period will benefit Neediest Cases Fund.
