Some time ago I discovered the site: Wordle, which creates word clouds from any text or from web sites you want. It works as normal word clouds (as if word clouds can be normal!): larger words are used more often, while the arrangement is left up to the idiosyncracies of the computer program. You have some control over display, but not a lot.
I have played with it privately, mainly with the purpose of self-criticism in mind, to try to get a different sense of what I am writing. Of course, these images include text of whatever I happen to be quoting.
I have found it enlightening to put in some text to see what happens. I thought I would share my latest one, based on the latest RSS feed of my blog.
