Design Coding: The SEO Rapper

I have to post this, because this guy is a) Awesome and fun to watch, and b) hitting on all of the points that I try to convince people of daily in my work. As a web designer and a bit of a coding purist, I have often tried to articulate the importance of clean, valid code in the greater business practice. Jeffrey Zeldman does a pretty good job, but I think my new favorite is the SEO Rapper.
