Interface was the more ambitious of the two books, and it probably suffers thereby. As it happened, my completion of the book coincided with Super Tuesday, and so I was perhaps more alert than I otherwise might have been to the demoralizing details of our primary "system." The Cobweb (published in 1996) is much more specifically situated during the run-up to the first (or second) Gulf War and almost tries to be an understated version of Tom Clancy, but sardonically funnier. Neither book is a dramatic departure from Stephensons style: neither provides a satisfactory ending, and both indulge in digressions designed to appeal to the Asperger set.
