I have a plugin which assigns categories to pages, so would like to know can that be used as a method of filtering? These categories will show up when a page is created or edited. This way would be more client friendly instead of trying to remember or cutting pasting meta data when the page is created. Post standardizes using categories, so I am thinking this would be consistent to use categories.
I think it would be grand to use both meta tags and categories as a way of filtering pages/post.
