I myself have found use of special features that only one web browser uses but that is only used on few select pages for the classes I teach online. Not all of your public is able to adjust their web browser in the ways you do. For example, most students and office workers are using machines they can not change the application helpers their web browsers are using. While working on the template page is a good time to think of the information you want on every page. It is important to have some kind of information on your site for people to contact you and to be able to return to your site later.
Many sites have more than one template.
If you think of your site as a type of heiracy, you may have templates for each of the branches you create. This site has a template that encompassed the main sections. When a section has to be broken into more catagories, an adjusted template is used for each one. You will see that by the general naviation system is the same in all areas of this site, but some of the catagories may have several sub catagories listed right below the main navigation bar which only work for that subcatagory. To give you an idea of the play you can do with a template.
