Contemporary to the birth of mass computing, e-health has essentially evolved around online services. The spread of broadband Internet has allowed the development of online communities and the emergence of a “collective intelligence” within networks of patients, especially for those living with chronic conditions. The Web is not only a mass of freely accessible medical information, it is the locus for a new epistemic and political alchemy. The hierarchical organization of science gives way to a horizontal, dynamic, and heterarchical structure of knowledge and trust. The term “health democracy” introduced in the French legal system in 2002 effectively typifies this development, heading towards patients’ empowerment.
