Wordle is the latest fun tool that has cropped up on the Internet. It makes 'clouds' from words you provide, or the tags you keep in del.icio.us.
I am not really sure how I would use this tool in a teaching context. Cathy Nelson thinks it can be used in writing classes to look at how words are used.
What I find interesting from a personal perspective is that I am saving few midwifery web sites in del.icio.us. The majority of my tags are to do with professional development, life-long learning, e-learning and PLE. This probably reflects my current interests as well as the fact that I read few midwifery blogs compared to education blogs.
