Found this thanks to Chris Brogan. The site Wordle allows you to create word clouds of your blog content. Check out my content. Interesting to see what i write about.

That is hot! I was wondering where people found this for their blog. Thanks
yeah its a very cool service. i checked it out just yesterday. did you change the colors right there on the site? the main add-on i didnt see that i think would be a cool value add would be allowing you to adjust the word count or specify alt text or links as the words. but im sure they are working to add more cool things to the site.
