What do you do with clutter? You clean it. You don't burn your house down every year because it's cluttered.
Wikis aren't free. Organizations need to take it upon themselves to continuously groom the contents and organization of their wiki. They can be very useful if you do. But it's an ongoing process, just like organization in any other area in life.
You don't write code in a single file and then delete it when it gets too big. You create folders. You move and prune. Sometimes you delete. Make it intuitive.
