A big thanks goes out to Michael Kalus for letting me know about a great little program called Kotoba. It’s a tiny thing that you keep open in the background, and it keeps flashing Japanese words or expressions in kanji, hiragana, and English. My biggest weakness is my vocabulary, and I’m always trying to find ways to improve it (and I hate trying to memorize lists of words). I’ve been running all night and I’m already learning some new vocabulary and kanji characters. Only for Mac OS X.
