This Twitter tag cloud or Wordle is aggregated from all of my tweets on Twitter so the words that I use more often increase in font size. Surprise surprise I use the word Twitter the most and even more surprising is my use of such positive language such as 'thanks, nice, great, good, love and hope'. Who knew? :-p. Also do you spot anyone you know in my @ replies?
You can get one too at http://www.wordle.net/compose.
