There's still some things that I'd like to add, but all the core functionality is there and working. So, I'd like to finally present you with .... CramDex.
CramDex is a flashcard studying tool. Of course you can build your own decks of cards and in the true spirit of Web 2.001, you can study other people's decks and they can study yours. Sounds pretty bland, but there's more. CramDex doesn't start out flashing all of the cards in your deck at you. It randomly picks a few, and starts you on those. It tracks your progress on each, spending less time on flashcards you know, and more on those you don't. As you prove that you know certain flashcards it starts to introduce more cards, and once you've demonstrated that you've mastered a particular card, it's "set aside" and only rarely shown again (just often enough to re-enforce that knowledge). So you're constantly focusing your efforts on learning new and difficult material, and not wasting time "studying" things you already know.
Initially, new flashcards are presented as a multiple choice question, showing you either the 'Question' side of the card and giving you several possible answers, or the 'Answer' side with several possible questions. After a few of those it starts to give you just the 'Question' side, and a field to type the answer into (spelling, punctuation and capitalization counts). The 'Question' side of the card can either be words (eg. "What's the capital of Mazatlán?"), or a picture. I've got one sample deck in there now that shows maps of US States and you need to identify the pictured state.
So, go check it out, pass the link to friends, and let me know what you think. It's still not very pretty at the moment, but I have to say, I think my design skills are starting to improve... just a little.
