- The Public Web – published pages on servers
- The Private Web – the personal desktop, which is now being integrated with search
- The Social Web – which applies the wisdom of Web users, both at large and in your social network.
This theme was woven through all of the presentations, showing that a common thread of many of the most interesting developments of search – and how it relates to the broader evolution of digital content – is that of user-generated organization of content. User generated content is becoming a major force, but what what promises to make it really useful – without burying us in drivel and irrelevancies – is user-generated organization of content.
We spoke last night of user-generated content and the Long Tail, of tags and folksonomies, of social networks, of reputation and authority, and of guides and recommenders. All of these relate to the real intelligence of the Web being not machine intelligence, but the ability of machines to help people share their human intelligence in far more powerful and efficient ways.
- Bradley spoke of Flickr and MyWeb 2.0 , and the culture of participation, with a pyramid of creators (e.g.: 1 in 100), synthesizers (10 in 100), and consumers (100). He also spoke of Yahoo!'s FUSE objective: "Enable people to Find, Use, Share, and Expand all human knowledge."
- Marissa Mayer of Google's comments reflected the inherent social web component of Google's PageRank system, which favors pages that are linked to by many other Web authors. She also noted the power of user-generated video in a world where millions of people have high quality video cameras and Final Cut skills.
- Karen Howe of AOL/Singingfish described the efforts to make all that video searchable, and how the descriptors users include with their postings aid in that.
- Salim Ismail of PubSub spoke of new ways to make user-generated content more accessible, including Semantic Web-based methods of "structured blogging" that can allow special content such as user reviews to be effectively searched and aggregated.
I have been a believer in the power of "man-machine symbiosis" since reading Licklider's classic article (and the hypertext visions of Ted Nelson and Doug Engelbart) decades ago. The Social Web, and this idea of user-generated organization of content, exploit the power in using machine intelligence to do what it does best, and applying that to augment the real intelligence that humans do best. This has been a long time in coming, but this aspect of "Web 2.0" promises to be a major step in that direction.
