The node http://manchester.openguides.org/?Category_Hitching indicates that people are confused by the prefixes. Category Hitching is not a category, it's just a node with that name in front. I suspect it's called that because the other links in http://manchester.openguides.org/?Category_Transport all start with "Category" and the user was merely following suit.
Oh, and it'll save all the hassle of writing [[Category Foo|Foo]] every time you want to construct a coherent paragraph which contains a link to a category ;)
