Scopeware: Knowledge management tool introduces new information-use metaphors

I picked this story up from The Standard. David Galertner's Mirror Worlds Technologies announced the commercial release of ScopeWare, a new information management tool that sits on the desktop of your computer and indexes, displays and allows searching of all of your data in any format. As a knowledge management tool, I find it interesting. I played with Altavista's personal search for while, and still found that organizing my data on my hard rive, in my bookmarks, and in my email folders was easiest using folders hierarchicaly arranged by subject/topic, project, etc. The metaphor that ScopeWare uses is likened to a personal journal. The tool displays your data in chronologically arranged "streams" on the desktop like a journal of your days' activities. They posit that people think in terms of "content and time, rather than file name or location." For me, that statement rings quite true, but I would argue that the physical arrangement of my folders (file name and location) maps to my internal cognitive mapping of the content; and that serves me fine. But, time IS another issue, and their offering seems not only to add that fourth dimension to your information-use experience, but it also integrates all of the information you use (email, web sites, documents) into one interface. While we're on the topic of interface, I wonder what impact their "time-streaming" metaphor will have on us interface designers? Will have to leave that discussion to a later thread after I've digested the concept a bit more.
