I just discovered this site, www.wordle.net that will show you your most used words in any piece of writing. It's so awesome! These are my most used words for nano 09. (I don't know how to make it bigger, but you can click on it to see it full size.) I figured those three names would be the most often used, but apparently I used Went, Looked, Think, Asked, Going, Like, Eyes, Just, Demon (of course) Around, Get, One, Face, Go, See, Back, Vera, and Still the most too. Probably the longest word in there is Enchantment.
I made one for my nano 06 too, and a lot of the words were the same :P Oh well. Also, I LOVE their fonts.
