I couple readers inquired about the image at the top of this week's “10 internet technologies educators should be informed about” post. I used Worldle (www.wordle.net) to create this image. Wordle is a free web based application that lets you create word cloud images quickly and easily. These are not true tag clouds, since the words are not links, but it is still a great way to create images similar to tag clouds. There is a lot of flexibility regarding layout and appearance, and the images can be exported in a number of formats. If this is something you think you can use, give it a try – it just takes a few minutes to create a word cloud of your own!
