This should really be made into a web service. Where all the new card decks are shared for free. I think it could become a very powerful collaborative environment.

Hi! It has been by a few people including me. My site is here: http://flashcarddb.com

FlashcardDB allows a choice between two spaced repetition algorithms: Supermemo's SM-2 (like Anki, Mnemosyne) or the Leitner System. New card decks are shared for free.

I use this when learning a new subject. It's insanely good
