If Gorgorat.com has permission to print the book, or it's now in public domain, then I'm the first to say link to that pup... but I didn't see anything on the site to say this.
I'm a bit surprised that folks who make their living creating intellectual property are so blase about this. There were more comments about the inappropriate affiliate link than the fact that the book is still in press and under copyright.
Let's not devolve into "information wants to be free" and "the world is open source", but stick to the fact that the book is not free and open source in the US legal system at this point, AFAIK. Would we be linking to a hosted full copy of PG's excellent book Hackers etc. (http://www.paulgraham.com/hackpaint.html) to highlight one of his points? Probably not.
