Hi, I like it, but not so much in the browser - I am expecting you will be making some sort of library app or make it possible to export directly to iBooks / epub at some point? If so I think it's great in the browser then exists as a fallback / place to check out the book before you actually put it on your device. In the browser itself the whole book metaphor has always seemed cumbersome - is the code for that modular enough that it could be easily switched out with other interfaces? I am envisioning it as sort of theming the 'book'
