Currently, the top three bestselling titles for Amazon.com's Kindle, Jeff Bezos's tree-killer killer, are newspapers and magazines: The New York Times, The Wall Street Journal, and Time magazine. Despite the fear that newspapers and magazines are dying, they are the most popular purchase on the future's book killer. These traditional publications are all available online, mostly for free. Kindle purchasers, in other words are spendthrift, hyperliterate gadget junkies who feel guilty about both the environment and the demise of old media. Who besides Craig Newmark is buying this thing? I can't wait to I buy a $20 Kindle on eBay — a past reminder of a failed future.
