A web developer and I are reconstructing a website using Wordpress, and she has asked if she can use categories instead of pages for organizing the site. The Home page will have 5 to 7 subjects in the main navigation, and each subject area will have many articles. In addition, there will be a blog for new articles.
My gut is that pages should be used, but the web developer is pressing me for a reason, because categories are easier to manage. The forum manager on the WordPress site clearly favors using a custom menu and categories, when assessing how other sites should be constructed. Is there any compelling reason to use one or the other?
