I just get such a giggle out of seeing what shows up in the Amazon "also bought" list on my book's page. Today (sales rank #16,123, btw), it's:
- The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography by Simon Singh
- The Cryptogram Challenge: Over 150 Codes to Crack and Ciphers to Break by Robert Allen
- Twisty Little Passages : An Approach to Interactive Fiction by Nick Montfort
- Rootkits : Subverting the Windows Kernel by Greg Hoglund
- Fortune's Formula : The Untold Story of the Scientific Betting System That Beat the Casinos and Wall Street by William Poundstone
Especially that "Rootkits" one makes me laugh everytime I see it. Yay, my geek fans are buying my book!
