Are there any medical schools or medical libraries (associated with medical schools) that are doing blogging in the PBL classes?

I thought a blog (a central, dynamic, information sharing site) would be the perfect tool for the dissemination of information and the fostering of discussion within the PBL classes.

I have sat in on a few PBL classes (at my previous library position) and there is a ton of information that gets discussed and researched. Each PBL class is given a case in which they must work through with others in their group. Often each group member does research and learns information that they then discuss in their next meeting. What I have noticed is that often their are notes all over the place, dry erase board drawings, and photocopies scattered all over the table. It occurred to me that a blog would be a great place to post all of the information gleaned from the PBL class sessions. This would allow all group members to have the same information in one central site and foster their group discussion and learning beyond the normal PBL class time.

So my question is, Do you know of any libraries or medical schools using blogs for this purpose? Please let me know.
