Immediately after reading the entry and contemplating the publication date, my first thought was, "Is it bad that my first thought of cryptography involves digital methods?" (I instantaneously thought of RC4, AES, DES, etc. It took a second to think of One-Time-Pads, Polyalphabetic Ciphers, and Caesar Ciphers.)
Okay, enough with the bashing about the McDonald's exploit.
Yes, it seems like small change when cast against larger and more profitable forms of fraud. But then, when you learn cryptography, you start with simple transposition ciphers, and then move on to more complex ones.
When you learn sleight-of-hand, you practice the small things and the basics.
Discussion of the McExploit helps people grasp security concepts and social engineering.
Almost worth the 6000USD to find out what is the difference between "scattering of letters" and "strewing of letters".
Maybe Bruces next cipher should adopt the terminoligy -- " And lo though shalt scatter the letters according to thine seed then thow strewest thine scattered letters about thine S-box unto the fourth and twentieth round. "
The reference implementation could be coded in LISP to make reading even easier.
