So I notice that you are taking images off amazon's API and are reposting the covers... how are you getting away with this. I had a similar idea that i half implemented and had to abandon because amazon's API policy is very specific about hosting and grabbing their images from their API. They also supposedly don't want you to cash almost any of their information ...
In the past year i have read at least half a dozen articles proclaiming various technologies dead.
The Web, Grails, Java, Telephones, ect...
PS I declare that declaring preemptive postmortems to be dead!
