] [#60] Elonka's List of Famous Unsolved Codes and Ciphers

I was checking my weblogs, and saw that my average hits/day jumped from 60/day to over 2000/day on my "Famous Unsolved Codes" page... Many of the links are coming from bbspot and metafilter. I'm not sure what started the meme today, but my guess is that I landed on bbspot as one of their "daily links", and it took off from there.

Whee!
