@nitinkhanna While I don’t use it, I don’t think there’s much of a chance that Amazon will shut Goodreads down anytime soon—it adds to their platform lock-in. As you mention, they’ve been integrating it with their Kindle ecosystem. Yet another advantage they have over iBooks and a formidable barrier to anyone else seriously competing with them in the eBook market.

Which is all the more reason that Goodreads competitors should make it as easy as possible to switch.
