If you are an Independent author, or even a published author thinking about joining Goodreads, I hope you will take a look at my free booklet and closely examine your motives before giving Goodreads, and thus Amazon, a bunch of free information that they will then own and control. If you believe that Goodreads 'Review' system is fair, you need to read about troll review attacks that are also documented widely on the Internet. And let me warn you about a number of broken features on the website that may affect your sales. The main thing you must understand, though, is that you are on the bottom of the food chain at Goodreads. You are the income that keeps the server farm humming but you are entering into an adversarial relationship, not only with the pampered readers but the overworked staff that doesn't even know their own rules when they punish you because there are so damned many rules and the documentation is broken, outdated chaos.
The booklet is short and free. It provides a lot of links to information on the Internet that you should know and links to the documentation at Goodreads. If nothing else, at least read the first page and heed the warnings in the links provided.
