In 2004 I started to think about how rich internet applications (RIAs), generic content models like RSS and web services were changing the page-based model of the web.
I gave an introductory presentation on the topic, which I called Beyond the Page, at an information architect's retreat in late 2004 (as well as a reprise at the 2005 Information Architecture Summit).
At the time I wasn't aware of anyone else who was thinking deeply about the impact these changes would have on information architects, interaction designers and other people who created web-based products. Nor did we understand how RIAs, RSS and the like would influence the metaphors we surf by.
Since then, of course, the web has moved from the page-based metaphor of Web 1.0 to the more fluid, Ajax-driven Web 2.0. Web widgets have become popular. And RIAs are not just common--they often rival their desktop counterparts.
Beyond the Page captured part of that evolution of the web--we knew something was changing, but web 2.0 hadn't yet taken hold. Here's the presentation:

Since then a number of people have tried to address the issues of designing and documenting interactions in a pageless world. Bill Scott's Designing for Ajax is a great introduction, and his work with David Malouf on Desiging RIAs is also excellent. The folks at Adaptive Path have also put together a good presentation called Beyond Wireframes.
