I have a slew of Ruby On Rails tutorials I am putting together. What I need to know is if there is actually a need for the content. Because if not, I'll probably make all of my tutorials into an E-Book or actual website. If anyone would be interested in a complete guide to Ruby On Rails that covers everything from installing to complex techniques, please reply and let me know how much you would be willing to pay for such a guide. Please assume that the quality is excellent, and that the tutorials all form a complete guide- so there is a LOT of content. Thanks!
