I created the image with all the words at the top of my page with Wordle. I just plugged in my Web site address and it made a cluster out of everything on the page, with the most-used words getting bigger billing. I guess the chlorinated chicken thing stood out. It's a lot faster to load if you just cut-and-paste some text in rather than using a Web site.
Thanks to Nathan at Polybloggimous for suggesting that I use Wordle to make the header. I had played with Wordle before, but for some reason it didn't occur to me to use it to make an image for the site. I'm pretty pleased with the result.
