Tool: Wordle

Wordle takes text as an input and generated word clouds. They provide three different types of input mechanisms:

1. Paste in a bunch of text: A text box to enter the text.
2. Enter the URL of any blog, blog feed, or any other web page that has an Atom or RSS feed. A text box to enter the URL.
3. Enter a user name to see their tags A text box to enter delicious user name.

Here too, the output cloud highlights the most frequently used words in the source text. Wordle also provides many options to tweak the word clouds with wide variety of fonts, layouts and color schemes. The output word cloud can be used by the user for personal use. Wordle provide options to print them, save them and also an option to share. Wordle also provides a feature to create a cloud from users personal webpage too. All you have to do is to POST the raw data to, with the parameter "text" containing the text. For example:

Clicking the submit button will display the text in the image in a word cloud (The POST is not working sometimes :(. Some problems with the site).

Wordle greatly depends on JQuery JavaScript library. The data input can be done in any form as I have stated above. This kind of word clouds help a user in figuring out the most frequently used words, important words, popular words etc.
A Wordle from the feed of my blog is as follows:
