Read it. If you don't do it now, you'll kick yourself when you finally do.

I found the book entertaining as well. One problem for me was that I had already read a lot of the real cypherpunk material, and the book was rather tame in comparison. (It's fiction, so it has to make sense.) I also thought the book would have been better a few hundred pages shorter (it is over 900 pages), but it was a nice leisurely change of pace from my usual 350-page books. (Even the book's FAQ says "the book is lengthy and somewhat discursive".) Perhaps I was just too familiar with the material--much of the "crypto" material was about as exotic to me as a description of a cellphone would be to most people. Most people don't have AppliedCryptography on their bookshelves, however. --CliffordAdams (still on the "coderpunks" list)
I had much the same reaction, to the material on zeta-functions: this used to be within my professional competence. I finished the book, somewhat regretting having spent the time though. Not a book worth rereading, in my opinion. -- CharlesMatthews
By the way, the unofficial FAQ for the CypherPunks mailing list is called the Cyphernomicon.
