Hard to know which is more alarming:Amazon.com's willingness to flout the privacy of people using its Kindle electronic readers, or its imperviousness to irony. The world's biggest online bookseller floored Kindle users when a major publisher changed its mind about allowing an electronic edition of two of its books to go out.

The titles in question? 1984 and Animal Farm, by George Orwell.
