Kindle... I don't know, it seems like just another tool that's going to bring on Mike Judge's vision of homogenized retardedness presented in Idiocracy.
I just found out recently that the large corporate book sellers actually have say in book covers and editing, and I'm assuming their dictations to the publishing houses is based on their sales figures. Example: The man in on this cover is wearing a brown suit, but our figures say that people buy more books with men wearing blue suits on the cover. Tell the publisher we need the cover changed to a blue suit.
Now, if the Kindle can delete your content, who's saying that it's not capable of reporting on your reading habits? I mean, we all know of course that they'll know what books we've purchased, but what's going to keep them from data mining what books have been read to completion, how long it took to read, and whether specific parts were read more than once? In my mind the results of such data accumulation would be a fucking disaster.
Could you imagine a world where everything published has been created only to satisfy a data model based on the type of shit the average person reads most?
