Developing With Web Standards by Roger Johansson is just a TOTALLY AWESOME summary of what we should be teaching web design students as best practices. I would tell you to print this article and give it to all your students, but there are so many valuable links in it that it is better to use it online. Many of the references included for further study are links I have mentioned here previously, but it is a great service to have this all gathered into one intelligent and coherent article and resource. Listen up, publishers! This is the curriculum we need to be teaching.
