I ran across an application at http://wordle.net that
will allow you to paste in a bunch of text, the URL to a RSS or ATOM feed, or a del.icio.us
user name and it will read the text, remove common words, and then create a word cloud.
I created one for my blog.
The most surprising part of this word cloud to me is that the largest words don't
necessarily match with the tags that I have defined. I think I will have to rethink
my tagging system to make sure that content is easy to find.
