Great site, Emma!
Just a word of caution in case you aren't telling students this. Anonymous medical blogs seem to be particularly vulnerable to being tracked down and exposed. I personally know of two recent situations: one student "Barbados Butterfly" who was mildly critical of her training and was told to shut her site down and a pediatrician, "Dr. Flea" lost a malpractice suit because he was asked under oath if he was this blogger, who had been commenting on the lawsuit. Blogging gives an aura of anonymity which is quite false evidently.
