Smart.fm

This is a very useful study site for any flashcardable material. The thing that really blew my mind, though, was the audio samples for nearly every word I input. (I'm EmaWii -- so far I have made a list of all the words I am looking up from the first grader kanji くもん drill book.) It's pretty fantastic, actually.

Supposedly the unaffiliated (i.e. using the API) iPhone app allows you to download all your lists, sound files intact, and study them away from the computer -- although the fancy quiz feature (which I haven't really played with yet) is not available...

Looking forward to putzing with all of this more. It's ten times better than anything else I've seen, with all these audio samples just sitting around. You can even create and upload your own, so I could make a list of English vocab and upload me saying all of it in my perfect native English. Sort of interesting.

Doubly interesting is the Twitter Vocab list. That said, I think I am going to create my own version. They seem to be putting in a lot of stuff that is quite targeted enough for my liking ("time?" really? That's useful, but doesn't have THAT much to do with Twitter).
