It's even more frustrating than that, currently, because when you finish a Kindle book, it asks if you want to tweet about it or post it on Facebook. I don't, but I very much want to post my rating of it to Goodreads, and that isn't currently an option.

This fixes a big hole that a lot of people (at least, a lot of people on Goodreads) have been clamoring for.

Definitely an obviously good acquisition.
