I'd love to give this a read from someone with a lot of experience in the source material, but given a $50 pricetag for a book I don't need to read I'm not into it. Who are your editors?
Would you be interested in giving it a read in exchange for your feedback? I might be open to that (DM me https://twitter.com/strzibnyj).
I already lost more then one year of earnings working on the book and I couldn't afford a professional editor. So editors are only volunteers, and therefore I don't have a single editor for the whole book.
(I know that as a potential customer you don't care about my excuses, I am just explaining my situation. Earning money on technical content is hard.)
The pricetag doesn't reflect just the PDF, though. If you deploy your own database with the demo, you might save way more money in a year. Other similar resources include less and charge more, or do you know one that's better value?
I didn't split it into tears (book, book+code, book+code+...), because I think it works better together. I do realize I am losing some customers this way.
