I’ve been looking into what SL might have to offer education for medical and other health sciences professionals, since I heard the suggestion that it might be good for PBL. I though that notes of my preliminary researches might be of interest to others: 

Three places to find out more about who’s doing what:

Three sources of blogging in, about, for or with SL
