What is it about this image, other than the fact that it is a visual representation of my del.icio.us tags, that is so compelling to me? Imagine each of these tags as an active link that connects me to my bookmarks and the bookmarks of others using the same tag. Imagine that this is not a series of tags at all, but a clickable navigational map of course content in a course entitled Ideas & Methods in Education, and that the words assume their hierarchical presence according to students’ contributions to the “discussion/conversations.”
