(While thinking about this, I thought back to an earlier discussion on this list (or possibly wikien-l, can't remember now) about the fact that there are essentially two types of categories: thematic and taxonomic. For the former, the "tag" model of atomic categorization is quite natural, but the latter would fit much more naturally into a strictly hierarchical model. It might not be an entirely unreasonable idea to formally split the two, perhaps even into separate namespaces, and apply different technical approaches to handling them.)
Doing that would probably help in advancing with the system.
