Shell and Zeitgeist: the future of GNOME?

Yeah, if people can't be arsed to put they files in a sensible folder structure then they won't bother to richly tag them. All such meta data should ideally come from the file content itself. E.g. id3 tags, exif data etc etc. The ability to have live projection with many, often pretty complex constraints (i.e. you need a full expression engine in this, not just some "show me files tagged with 'red'" crap) is actually pretty cool.
