Category talk:History of journalism by country

"by" categories have only one parent.
The purpose of metacategories ("by" categories) is to divide the content of a category according to some property. A metacategory is not a distinct category from its parent, because it encompasses the same articles. A metacategory is simply a folder for organizing subcategories of the parent category, so it has no direct connection with other metacategories. Metacategories should never be children of other metacategories. &mdash;Coder Dan (talk) 12:06, 1 August 2014 (UTC)
