I wanted to suggest interviewing Michael A. Nielsen, author of "Reinventing Discovery: The New Era of Networked Science."
I heard him on Science Friday. He's written a book about science being performed "more in public," so knowledge in science is much more like Wikipedia. On one hand, I think that's a great idea, since it seems to me that journal articles are too difficult to get for the lay person and that the infrastructure of science knowledge seems fairly antiquated and clunky. On the other hand, knowing that science is often politicized and that there are numerous individuals who would willfully wish to spread dis- and misinformation about certain scientific concepts and discoveries, I would wonder how this "more open" science would work.
Most people take for granted that Wikipedia should be viewed with a dose of skepticism, despite being constantly checked by the "hive." But a Science Wikipedia has potentially much more on the line than an article about Jim Carey, G.I. Joe toys, or the history of Baltimore.
