Interesting project using people's wish lists. I pondered this aspect of Amazon some time ago, and came up with my own personal solution. I have thousands of random items on my wish list (a few of which I actually wish for!). If anyone wanted to 'analyze' it, they wouldn't come up with any kind of accurate conclusions.
In any case, you should realize that your wish list, if you have one, is available for perusal via scripts.
