...To me the new killer app for the Internet should help me in working at any levels of abstraction. The higher the abstraction, the more volume of complexity and data I can handle. Also at any level of abstraction, I should be able to navigate between concepts that are visible at that level and observe new connections that were not apparent to me at a different abstraction. And when I want to dig deeper, it should help me in exploring more on that subject. At the lowest level of abstraction, it would resemble a browser. The mass of the content that is on the Internet will still be on HTML, which is doing a good job of capturing presentation information, and a browser is suitable to view this. In short this application should act as a seamless extension to mind and help me in generating ideas by creating new connection between concepts about which I have little or no previous knowledge by leveraging the collective intelligence of humanity.
