I like the idea of your book but you seem to be spamming HN for free ideas that you can use to capitalise on. Unless your book will be totally free? I like HN because people can talk about tech without having to feel like you have to pay for it... most of us I believe use HN outside of work or on our downtimes.
Please don't let HN become another internet marketing forum.
