If you need data to be available in a way that doesn't fit the document-based structure (in what MongoDB would call a View), you make a new JSON document that pre-caches the data when it changes (i.e. `blog/index` is a high level cache of basic blog entry details, like their subject, creation date, author ID, etc. -- but not their contents, comment counts, avatars, or other details)
