I'd very much appreciate a system like the one described as well. And I've got some further ideas. When tagging, suggested tags should be very smart - like Amazon/Netflix recommendation system smart. It should be backed with a Bayesian categorizer or similar. This sort of categorization engine could also be used to recommend hyperlink targets between sources when a term is selected. It definitely needs to integrate with the web browser. Highlighting a web page extract and saving it should both save the extract to the knowledgebase and also mirror the entire page in the KB so that later you can hit a 'context' button and be given the original source it came from. Trust as little as possible that the content will remain available and unchanged. I'd also like for there to be a 'bulk' area where things like entire books for future reference material could be saved reachable by the searching functionality. An automatic chronological index would also be helpful. If I save a page about fractal image compression and from there move to wavelet compression, being able to see the history of what order the topics were visited in would be beneficial. Integration with learning assistance systems would be nice as well, things like the various apps that use intelligently timed repetition of information in order to help with memory. I do think that building from a wiki could be a possible start. My biggest concern with using a wiki or other web based system is the terrible layout options forced upon us by HTML and CSS. They are designed such that arbitrary layout is quite difficult, and arbitrary layout would be fairly necessary for this.
