Great stuff! I agree that this is a key challenge. I have one answer, although it is much easier said than done : create more rich contexts, where more advanced filters may evolve, some of these socially produced, others more mechanical of nature. Wikipedia and pages on Wikipedia are examples of beginnings of these kind of rich contexts with advanced filters.
This can enable people to quickly locate information they need, and even find information they didn’t know they needed. Contrary to search, which is always a very conscious affair. Already, I often find stuff faster via sites such as Wikipedia and del.icio.us than on Google, especially if my query is a little more specific, or if it is, but I have too little to go on, in order to really search for it.
How do we do this? By giving these kind of hubs a business model. They don’t have one now. At Kaplak we will provide one model for sites/contexts like these - which will help information producers as well as the context hubs, mediators and filters.
