Wordle is one super-cool online web 2.0 service that lets you create a fancy word cloud out of a piece of text or your Blog feed.

Just like a tag cloud, it picks all of the high-frequency words in your Blog feed and arranges them in a stylish manner in order of their occurrence. The only difference is that unlike a tag cloud, words are not linked to tags on your blog.

The service also lets you choose the font, color and orientation of the word cloud and even lets you print it.

Moreover, Wordle has a wonderful gallery of word clouds where you can see the word clouds generated by other users.
