Tag cloud addition

Been playing with tag clouds recently and just added one to my blog (see the sidebar). Do you use these? What do you think of them? I found the code for mine at phydeaux3 which has pretty simple instructions if you can read CSS. Toward the bottom of the article, there's also a trick to specify the frequency terms should appear on your blog before they show up in the cloud (otherwise it can get unwieldy).

If you think Tag clouds are pretty (as I do), then you might like Wordle which creates Tag Cloud images of any site or text that you feed it.

Here's one I made based on my site homepage:

Oooh, pretty. Yes, I know. I'll say it for you: Dork. But that's why you keep coming back, now isn't it?
