I believe one of the most important themes for our future is collaborative filtering – I will keep on coming back to and developing this theme on these pages. This is fundamental to the formation of what we can think of as a “global brain”. As I describe in Living Networks, one of the most important functions of the human nervous system is to filter the massive sensory input it receives so that we are not overwhelmed. Similarly, in a world of massive and increasing information overload, we need mechanisms that make what is useful obvious, and what isn’t useful invisible. By collaborating on this task, each of us can benefit from the perceptions and judgments of us all. (Read the book sampler on “free downloads” page for more info.) Those that help create a higher level of collaborative filtering will add massive value – and with the right business models can extract part of that value. Discrete examples include Amazon.com’s book recommendation system, the Movie Lens film recommendation service, and Media Unbound music personalization system, used by Pressplay and mentioned in my book.
Which takes us to the much-discussed Google acquisition of Blogger. Steven Johnson has written an extremely interesting article on this for Slate. In short, he suggests that Google can pick up how people navigate the web in order to draw meaning for themselves and others. The analogy with the brain is that our repeated trains of thought are not only remembered more easily, but are also the very foundation of our neural pathways and thinking. I’d go further than Johnson to suggest that applying these approaches on a global scale could be critical in creating an information architecture that is far closer to that of a brain, providing highly effective filtering and the early stages of sense-making.
One of the key issues that emerges from this is that whoever monitors our information usage patterns to create useful tools, holds intensely personal information about us. Who will we trust to do this? Google-Watch for one doesn’t trust Google.
