By the way, I've heard the book "Design is a Job" praised on HN as a freelance Designer's guide to freelancing. I'm currently reading it. It seems your book is very similar in its goals and content, only for programmers instead of designers. If I'm right, I would definitely consider marketing it as "Design is a Job - for developers", or at least include that message somewhere on the leanpub page. I know I looked for it.
