Hi,
I do not understand what's wrong with the first [[Category:...]] approach.
Categories are kind of metadata - not all arguments against metadata apply on them. Categories are not hidden as long as they result in a link on top of the article or somewhere else - they are not more complicated than interlanguage links (which are complicated in some way).
Seperating categorisation and articles in two projects does not make categorisation more easy. In fact I'd also like to move articles and categories around in a hierarchal view but the most common action is to specify the category an article belongs to.
By the way categories are nothing but hierarchical links between articles. Semantically there is no big difference between dividing an article in subtopics and creating a category with a couple of articles in it.

Example: "[[Category:Stuff]]" somewhere in the article will show a link above (similar to language links), leading to the category page ("Category:Stuff"). That will automagically list all pages in that category (meaning, that link there via category link). A category page can be edited like a normal page (the article list is automatically shown below), and can include "super-categories" (e.g., "[[Category:Biology]]" on "Category:Zoology"). Any page can, of course, have many categories.
Ah - that´s the fault! The link [[Category:Stuff]] should refer to the article "Stuff" and not to some special-category-only article. [[Category:Biology]] *is* [[Biology]]! Please have a look at the actual article [[en:Biology]]: What does ==Fields of study in biology== contain but a listing of subtopics? Why introduce a new artificial namespace when you can better name the article for instance "Fields of study in biology"?

That's still possible with categories. There are a lot of automatic posibilities - most of them based on the links between articles. A special category-link would give more input.
What I'd like to see is an explicit wiki-statement of what is the desired functionality--that is, what is the utility missing--that a category scheme would provide.
Then we can discuss particular implementations separately--for example, is it better to use a system which has a single ontology or a system which allows for dynamic ontologies?
Argl! A wikiontology is a nice scientific project but nothing any normal human beeing will ever able to edit.

What I propose it that MediaWiki expand this metadata format to cover other types of metadata, such as:
- categorization -- saying that particle physics is in the physics category, or that Lord of the Rings is in the fantasy books category
- relationships between articles -- break up a single page into multiple chapters or sections, and note that they're all part of the same article
categorization is just a kind of typed relationship. I could also imagine:
[[see:A]] see-also-links that will automatically generate a backlink on article 'A'
[[next:A]] ordering articles
But hierarchical link are the most important ones.
