I recently learned that the meaning and reading of unfamiliar kanji can often be guessed.  If you’ve somehow managed to keep on and kun readings straight, you stand a good chance the readings of new words, or perhaps work out old words you’ve forgotten.  Example 町 is unkwown but has 丁 on the right side and you know the onyomi is ちょう .  you’ve just correctly guessed the reading  for 町 http://kanjidamage.com/kanji/57-neighborhood-small-town-町

What’s more, after reading http://kanjidamage.com/howto I find many answers to shortcomings in TextFugu (deeper nmonics for long or short vowel readings).  Perhaps at the expense of simplicity however, which is a potential problem.  But I’ll have to take a hard look at KD and maybe switchover to it for a while.
