The non-language topics desperately need to be reorganized. There are many duplicates (geography alone has three separate topics) and there are many courses that are in topics they don't necessarily belong in. And to be honest it's just sloppy. Is there any way all of these topics and the courses within them could be reorganized?
It seems like the best option would be to create major topics and then split those up into subcategories if possible. For example Science could be a main topic and as the amount of let's say physics courses becomes too large, the curators of science could create a physics subcategory, with its own dedicated curators. That way there could be a tiered system of curators that can oversee the system of topics at all levels, with a few at the top that could oversee the creation and management of the main topics. I don't know how difficult this would be to implement as far as the design of the website, or how much control over content the users should be allowed. And perhaps someone else has a much better idea for how these topics should be structured. I would love to hear some input.
I think at least some preliminary structure that allows for the evolution of new categories and at the same time keeps things organized is needed so that the wiki can be maintained as the content expands, not just on the word level but on the course and topic levels as well. And if it can be done soon while the amount of content is still easy to manage, that's all the better. But if the creation of a new system isn't very realistic could the current system at least be reorganized and then overseen to prevent duplicate topics and the correct categorization of each course? I would be eager to help with this task any way I could.
