Wordle

From those of you who've looked at TRIP Answers cannot have failed to see the large tag cloud on the site. I like tag clouds as they allow you to immeadiately see trends in data as well as aiding navigation.
Last night I came across the site Wordle which analyses text to create tag clouds. The initial link I followed to get to Wordle had used the titles of over 150 session titles at an economics conference to see what the themes were. So, the image below (click to make bigger) is a Wordle-generated tag cloud of words in this blog.



I have also pasted all the titles from Cochrane Systematic Reviews to look for themes.




I'm actually interested in what conditions Cochrane explores, so have removed a number of the main terms such as intervention, versus, preventing etc to obtain a tag cloud more to my liking.
