This is an interesting approach:

Let’s face it. Technology moves fast; academia doesn’t. So how do we teach web design and development—a subject that is constantly changing? How do we prepare our students for the real-world and for real-world expectations? And how do we, as educators, stay up-to-date about the information we are teaching?

The best way to approach this topic is to seek the expertise of leaders in the web design and development fields. As the people who will hire our students, they should have input about what type of students we are producing. With that in mind, I interviewed thirty-two leaders in the fields of web design and development, each of them is acutely aware of the importance of formally educating the next generation of web designers and developers. (my emphasis)

Rather than trying to put a curriculum together, why not just go to the folks who are practicing the art, ask them each five open-ended questions, and let them create a running text book of what is current thought in web design? Why not, indeed? While it's not quite the same approach as Wikipedia (there's no peer editing, for one), it does lend itself to a certain democracy by virtue of the over thirty respondents.

 The interviews and the rest of the site are prepared by Leslie Jensen-Inman, an Assistant Professor at the University of Tennessee at Chattanooga, who teaches a mix of art, design, business, and technology.
