While it's interesting to see the affiliate script flipped on Amazon, with their redirecting traffic to purchase the ebooks (surely with a nice cut of the revenue), the user experience leaves a lot to be desired, especially if you're used to purchasing your ebooks via the Kindle itself and/or the apps. The whole setup seems to be targeting hardcore fans—most of whom have probably already downloaded the ebooks for free via a torrent site—while asking the more casual reader to jump through hoops Amazon and B&N, in particular, have worked hard to eliminate.
Since publishers are so concerned with the “perpetuity of lending and simultaneity of availability” of their ebooks, I have to wonder if libraries shouldn’t just help them out and hit the STOP button themselves? Stop buying ebooks across the board, at any price, under any terms.
Amazon has always understood that readers are the most relevant market and that's why they're in the position of power they're currently enjoying. Do they wield their big stick aggressively? Definitely. And so did B&N and Borders before them, and presumably whomever the boogeyman was prior to them were guilty of the same thing.
If you're an author who has already been shook and sold your soul and firstborn to Jeff Bezos, I can see this seeming like a good short-term deal, but the potential repercussions are huge.
Much like Google didn't disintermediate big ad agencies via AdWords, nor TV networks or Hollywood studios via YouTube, but instead provided new channels for those who had no need for the Super Bowl, Amazon has done the same for authors who are better served with a scalpel than a mallet.
