I've begun work at wikipedia on "pandemic preparedness." I believe that pandemic preparedness needs to be done socially as well as through health services.
With regard to the recent tsunami, Wikipedia played an important role only after the tsunami had struck. Now, we have the opportunity see some community preparation before a pandemic.
For what is worth, there is a blog on avian flu, so there is some ongoing preparation. I wonder whether ProMED-mail subscribers, with their wide and deep expertise, can help guide that process and make it the best possible undertaking. In times of panic, I believe it will help to have some "blogging champions" all over the world working on this issue.
