You know I am a fan of word clouds as they show some great insight with an instant visual. Whether they are used to visually display frequency of blogging tags or the text of United States Constitution, they do in a split second what would talk often countless hours of research.
I heard about twittersheep over a month ago, but just finally got around to running their word cloud application. This site takes the personal profiles of everyone following your twitter feed and creates a word cloud. I find this visually extremely informative.
Who is following you?
