Very cool attack on the problem.<p>I&#x27;ve been working on ideas for managing filesystems and tools for thought for a while off and on, it&#x27;s starting to coalesce into a set of design ideas as well as prototypes.<p>What I won&#x27;t do is set up a filesystem: I don&#x27;t think that adds value to me; it mostly sounds technically complex and hard to figure out. And, I think that driving the whole business through manual tagging is a lost cause. Manual tagging can be _useful_, but actual attempts to derive semantic knowledge will be _more_ useful. I have many thousands of documents - manual tagging ain&#x27;t gonna happen.<p>I need _semantic_ search and _semantic_ cross-referencing; something like a Xanadu or a (much better) wiki&#x2F;hypertext system.
