Looks like a pretty cool app! "Amazon-free Goodreads" is a pretty good pitch. I'm curious how freemium model works out for them though, I could imagine a lot of people thinking the free version is good enough for them.
i just feel really behind on my book reading :/ havent read a good book in like a year.
Reviews are a by product IMO. I mean Goodreads reviews setup is horrible, no screening, nothing helpful in the implementation, etc
