I’ve been writing an article on Web 2.0 and evidence based medicine, which will appear on this site once it is published.
In the meantime here are the resources I came across, should anyone be interested:
Evidence based medicine: what it is and what it isn’t BMJ 1996;312:71-72 (13 January)
How web 2.0 is changing medicine BMJ 2006;333:1283-1284 (23 December)
