You bring up a good point. Just because someone knows how to program in HTML, PHP, ...etc, or simply know how to use a WYSIWYG editor does not mean they know how to design. Website design is like an art, however, people to do have the ability to learn the skill of making the art. As you do it over and over you get better at the programming, at the design part, at the organization of the website, and one of the most important parts, the content.
