Imho the most important problem of our current system is intersections. Category:Churches gets too crowded so we intersect it with locations (I even wrote a bot to do that). This "hides" a lot of images. We want to add atomic things, let's call them labels. So I want to add the label "church" and the label "Amsterdam" and have some clever software figure out the intersection.
Actually, if tags dont get a hierarchy of themselfs intersecting is one of the features I was planning to build in the Extension (or build in an existing extension if it exists).
One could search for a tag, and another and another narrowing down your search.
I can't imagine how many times I was looking for something simple and being forced to make a specific choise in order to see a picture.
[[Categorie:German scientists who won a nobel price]] Such a category could potentially exist on Wikipedia or Commons.
Instead such a photo could be categorised in: [[Category:Scienco Foobar meeting 2009]] Tag: Scientist, nobel price winner, german
Now for that reason I don't think replacing categories all together is a good thing. Think of categories as sets, pictures that belong together beyond visual similarity.
I mean a tag like "Wikimania 2009" would too specific imho. That's ideal as a gallery and/or category. But how about a category: "Groupphotos taken during Wikimania 2009" ? Too specific. But categorizing images of the event in "Wikimania 2009" and tagging some photos with 'groupphoto' . That would be nice.
