Seriously. Check out what Michael J. Newman has done with it (including the website above). He can teach you, too! It goes way beyond what you think it is (a blog template).
Not only is WordPress a fantastic way to get your portfolio online, but it's an industry tool for building websites. Yes, you too can do web design! Really.
And, it's taught in the lab on our fancy new Macs, with a teaching assistant at your side. Here is the course description:
Design and Development for WordPress: Beyond the Blog
Art 4 units
WordPress is a popular tool for designers and developers alike that has grown from an open source blog application to a powerful and extendable publishing platform. The WordPress community has created hundreds of freely available themes that allow you to change the look and feel of a WordPress website with ease. Modifying existing themes and creating custom ones can facilitate rapid development of dynamic websites with stunning graphic design. In this project-based course, students design and develop a dynamic website utilizing WordPress as a CMS. Concepts include WordPress fundamentals, creating custom themes, designing for dynamic websites, website maintenance, and extending WordPress.
Leading you will be Michael J. Newman, a designer who has developed and created original content, brand identities, interactive experiences, and creative solutions for such companies as AT&T, Sundance Channel, Vh1, Nickelodeon, and IFC, for over 12 years. To read more about him, go here.
