Brainstorming!
Fragment of a discussion from Talk:Workgroup:Categories/Proposed map
After my recent foray into ontology, prompted by the Shirky article [1] (related discussion thread, I understand how NOT pre-determining the category structure, and allowing users and authors to create the categories and connections that they need, creates a more powerful and effective structure for finding what you want.
Nevertheless, we should try hard to word whatever top categories we come up with to reflect our best sense of what will be most helpful to the community, although I suspect it will take some trial and error ;).
