I am about to take my daughter to the dentist and I was wondering if I could find a straight forward learning event on her procedure. She is being examined for a bridge to replace her two front teeth that got knocked out. There is some general information, but it really isn't good or clear or concise... There could already be a great learning event but I can't find it. It would be interesting if a dentist where to do a podcast on specific procedures. I saw a some of this in medicine already, but the trick is that the metadata has to be robust enough for me to know that it is related before I download the mp3 file.
Anyway... still a lot of room for improvement in learning application for the internet.
