> The crypto challenges were how we (for instance) hired Alex
But that's the use from your (or Matasano's) perspective. I joined the crypto-challenges not at all because I want a job in security, but because I continuously heard people be super-enthusiastic about it (both the participants, as well as yourself, tptacek :) ), because it reminded me of the old Malattia+ 3564020356 puzzles (level 6!), because it seemed more fun than the Euler Project puzzles (which I did enjoy, but you can only solve so many palindrome prime puzzles before it gets tedious) and of course because I would learn things about practical crypto.
Unfortunately I only got halfway the first set of the Matasano challenges, but that was more because I did it in Python and at some point got frustrated by its lack of speed :) (even using NumPy) I did make a rather elegant English-text MLE detector using a log-probability frequency table of only 256 bytes :) I thought that was pretty cool. I might have another go at it and this time use Java instead.
