wordle and tagcrowd

Okay, I spent a lot of time trying to navigate these websites and I did not have much luck. Wordle seems a lot more user friendly than tagcrowd. It also seems like a website that would be more appealing to students to use because of the examples it shows. Wordle seems like a good tool to use to help students be more active and aware of the words they are using when they are writing. It will lend them to more creative and use their vocabulary skills as well. I think that this could be a good web tool that could be incorporated with Thinking Maps to help organize students thought process and writing process. I need to have a personal tutorial to show me and help me navigate and understand the websites better.
