I really appreciate Raganwald's willingness to put these essays together into a convenient format and give them away. I enjoyed and probably learned a lot from them.<p>However, the publisher has not done its job here. I'm reading the Mobi version on Kindle for iPhone, and the constant formatting errors make it difficult to follow the text. This includes missing punctuation, missing indentation on blockquotes that make it impossible to see where the quote ends, random font changes in and out of a monospace font, random spacing around headers, and the lack of a table of contents.<p>If you want to call a collection of blog posts a "book" and ask for money for it, you need to at least proofread your output files and make sure basic standards of copy-editing hold. As it stands I will avoid buying from Leanpub in the future.
