The Piracy Calculator seems to have gained 20,000-odd hits overnight. I guess you can never tell right away how popular a page is going to be. This was quite a slow burner - I put it up in June.
I will see if I can add some currency conversion links and a counter for videogames to the page when I get a free moment. Also, can I just confirm right away that there is absolutely no risk involved in filling in how much stuff you've pirated. You can check the (extremely simplistic) script if you want and verify for yourself that none of the information entered even leaves your computer. Pirate on, dudes!
