We are now in the midst of a very innovative period of social and technological change that is being partly driven by the increasing availability of web based tools that support the development of relationships, the sharing of information and experiences of all kinds, and the manipulation of information on a scale that was difficult to contemplate just a few years ago. The experiences we have online are taking on increasingly important roles in terms of individual emotions, financial consequences, and personal relationships. There have been other periods of intense social and technological innovation. One of my favorite ones for study is the post Word War II aerospace industry.
