Here is a video by anthropologist Michael Wesch which explains “Web 2.0 in under 5 minutes”.  It illustrates how text has evolved from paper text –> digital text –> html (in which form and context are intertwined) –> xml (in which form and content are separate, meaning that users can upload content without knowing code, etc.) and –> the role of users in tagging and categorizing all the data we are producing. I thought the video was interesting in terms of Participation and the Web because it defines participation not in a political or social sense, but in the more mundane sense of content creation and organization.  It also highlights the presence of machines in digital participation. Dr. Wesch is the keynote speaker at this year’s Open Video Conference in NYC, Oct. 1-2, 2010.
