“There was an interesting post by Steve Brown on the Brown 2020 Blog titled, “Health 2.0 Makes Information Therapy Possible.”
The argument basically goes like this: If information therapy (Ix) is about delivering the right information to the right person at the right time, the complexity involved to make the information prescriptions personalized enough to be effective for each individual requires the production and prescription of Ix by “co-creators, selectors, navigators, recommenders, and reviewers of content”.”
