It's useful to remember the variety of possible meanings of "structure":
There are many ways to use structure in website design.
If you use more than a few dimensions and combine them, you end up in a mess of navigational pages.
If you use a strict hierarchic structure, you end up with a huge number of pages per level or with a scary level depth.
In my opinion a good structure must fit to the specific section of the page. This can cause unintended consequences on a huge scale.
The challenge is to automate the creation of navigational elements and URL structures by recognising important patterns and semantic relations. Standardising on-page elements and reducing the variety of elements could be a first step to organise huge sites.
