Thinking of Publishing Your Own $0.99 Kindle Book?

An anonymous reader writes "There's been a lot of talk recently about $0.99 Kindle eBooks, after publishers were accused of spamming the market with low-quality titles. Author Keir Thomas published two $0.99 computing books in March and has some figures for those who might want to have a go, as part of his Adventures in Publishing series of blog postings. Thomas says he loves the democratic nature of the Kindle Direct Publishing system, and points out one of his self-published books tops Amazon's Linux charts, besting titles by all the major publishers."
