According to their site, it’s a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text.
I like it because you can play with the design — tweaking your clouds with different fonts, layouts, and color schemes.
The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends. Here’s one I created using the content from my micro-communities post.
And another using the content from my post The New Normal Isn’t So Normal.
