I’m just starting to explore the possibilities of this, but apparently, if you wanted to, you could make each post category and each page look different using body_class and post_class. Separate page templates are for dramatic differences like leaving out sidebars altogether. That page title increase you had, Bruce, was probably the result of a body_class styling in the CSS, that said if the H2 was part of a page template, it should be X size, but otherwise Y size. You need to create a new CSS class for the new page with the same size attributes as the original. (I’m not explaining this well, don’t have the book next to me and am not practiced with it.)
