Does Amazon make any significant revenue from Goodreads? I can see how it might be something that boosts their kindle sales but other than that they probably have a good reason not to focus on it like... because it isn't a business breadwinner. Why work on Goodreads when you can make more money on AWS? Does anyone really believe they are going to become the next hot social network because they nailed the market for people who read books in the most transparent/ community accessible way possible?
