Wiki is similar to the blog. I have not had much time to play around with my wiki, however i am determined to become familiar with it. Blogger is a lot easier for me but i have been using blogger for a few weeks now and i hope that wiki is just as easy. Definately a structured learning design. This would need to be modelled for younger students of course. If the resources are in place and the teacher is supportive of the information needed this could be used as a personal or collaborative learning place.
