Web 2.0 … The Machine is Us/ing Us is a great short (4.3 minutes) video on digital text, hypertext and XML. It makes the point about how XML and tagging enrich text with knowledge that can be manipulated in innovative ways. The video does this by showing the editing of text where what is typed is the message and demonstrates the message. This is by Michael Wesch, a Cultural Anthropologist at Kansas State. See the Digital Ethnography group blog his is part of.
Thanks to Terry for this.
