Chris Anderson, author of "The Long Tail: Why the Future of Business is Selling Less of More," has a great recent post about the power of digital/hypertext/web2.0/socialnets. This is actually just a pointer to a YouTube video created by Michael Wesch, Assistant Professor of Cultural Anthropology at Kansas State University.
As the Kansas State University site indicates, Wesch is currently launching the Digital Ethnography working group at Kansas State University to examine the impacts of digital technology on human interaction. The first outcome of this work was a short video called "Web 2.0 ... The Machine is Us/ing Us." The video was released on YouTube on January 31st 2007 and quickly became the most popular video in the blogosphere.
This is just a marvelous illustration of the use of video/media to illustrate a collection of key points that would otherwise have taken multiple courses to teach. Some of the points are practical/technical. Some of them are quite philosophical. But taken together, the presentation is profound. Great stuff!
