Light reading and full of ideas but nothing that grabbed me. An interesting part was the social networking and web-site as part of the solutions to solve certain puzzles. Example: a disease/health condition not significant enough for serious research by big pharma; create a web site for people to log their experiences in dealing with these disease/condition, such as what foods worked/didn't work. It reminds me of the concept of "evidence-based medicine" which the health-care industry hates. So it was a nice story in the pantheon of the MIT Media Lab.
