It's an excellent text to be sure, but I wouldn't call it advanced. PCL was the the first real Lisp text I read, and I found it to be a superb introduction to the subject.
Whether it's interesting in its own right or not is not the issue. The subject matter is of a political nature, and doesn't really afffect or concern the technical community moreso than any other demographic group. Shouldn't this sort of thing be left to mainstream sites? In any event, most readers proably check other news sites, so this just seems redundant.
