Build three versions of an app with these characteristics using Ruby on Rails, Python, and Node and I pledge I would buy the resulting book for thirty five dollars. Try KickStarter. I funded this book http://s831.us/105pQB8 http://s831.us/105pQB8 and I am glad I did. I would pay at least five dollars up front to fund the writing of such a book.
