I just discovered Wordle, which is a free, web-based tool that allows you to make your ideas visual. You can paste in a paper you've written, a journal, an article, or even a URL to your blog. Wordle then takes all those words and analyzes which ones appear more frequently. The more often a word shows up, the larger it appears in your ‘cloud.'
The cloud above is from this very blog… but you can go and try it yourself with your own words.
