Mindboggling or mindblogging?

Just spent an hour looking at blogs to add to my Blogline. I searched for Spanish teacher blogs. I would like to find a couple that work for me with information and an exchange of ideas. Several of them are blogs being used by high school and university Spanish teachers in classroom situations. Each student has their own blog on which they will make postings in Spanish. It is mindboggling trying to sort through them all. But I like the idea of students blogging in the language. The teacher could create a prompt to which they would respond, or I even like the idea of just a free form communication, like a diary.
