Via Cameron, this New York Times column titled Internet Companies Reinvent Math. What grabbed my eye was the tale of the guy who's been trying to buy advertised computers from vendors with low prices one one of the price comparison sites, who take personal information then won't ship the computers claiming that they're no longer available (despite continued listings on their web site). A reiteration of my claim that most vendors don't want to make their information easily accessible.
