I recently gave a talk at the Web 2.0 conference on Spiral Web and how it can help us predict what is coming in the future for websites. Spiral Web is based on Spiral Dynamics and Memes, which are theories of how ideas spread among people. I have extended these ideas to websites for Spiral Web.
The 30 minute video of the talk is available at the Web 2.0 site (with free registration). The URL is http://tnni07.thenewnewinternet.com/agenda (scroll down to the 4pm slot and click on the little video link to the left of the 4pm text)
I plan on expanding on this subject at CFUnited this summer.
