Agreed -- correlating the amount of Kindles resold on Craigslist to a population's "e-literacy" seems tenuous at best. There's a buncha variables in play when you're considering the types of people who 1) are on the Internet, 2) are using Craigslist to resell, and 3) have Kindles to resell. If anything, I'd observe from the data that college towns resell their Kindles a lot more because the students are receptive to new/hip tech, collect their data point, and plenty of them move on by reselling via Craigslist, which extracts more value over eBay/Amazon, with some opportunity cost of time (to fulfill the order by meeting in person and what not).
