What you are seeing is a Wordle for this blog! As of August 1, 2008, the 100,000 wordle had been created. It's rather like a tag cloud for web pages, blogs, lenses, or a compilation of text that has been submitted.
You can create your very own Wordle by #1 pasting in text, #2 adding a web page URL, or #3 adding a del.icio.us user's name to grab their tags. Once your Wordle is created, you can customize the layout, font, and colors. Pretty darn cool if I say so myself!
