I'm definitely the target audience for this: I hate Goodreads and I still use it on a weekly basis. A couple questions: - where do you get your book data from? To my knowledge Amazon has a de facto monopoly on this and there's nothing more frustrating than missing latest or niche books, its covers, etc. or having wrong data/duplicates. - do you plan on offering a migration path? I've got years worth of data on Goodreads.
