Have you seen Wordle? Do you have your own? I think one of the coolest things is that you can simply type in the address of a blog with RSS or Atom feed and it will generate a word cloud from that!
LOL! I guess I shouldn't be surprised to see "Paperthreads", "SVG", "KNK", and "file" so prominent in my cloud. I guess I was surprised that I used "little" so often...hmmm...
