A word cloud scans a body of text (or a blog or website) for key/repetitive words and pulls them, then it arranges them in a funky layout. You can modify font, layout stye and color palette. If you're a blogger (or not) try it it you'll like it...also imagine doing it with a poem or interviews or anything! Its a fantastic graphic design toy!
If you make a wordle because of this post- leave me a link to it in my comments so that I can see it!
