Content vs. presentation

I got myself involved in a discussion that's tangentially about content vs. presentation on Ryze and StopDesign has a timely article on the subject. I'm currently working on a new stylesheet for my pages (including this one) and thus far I've managed to change the appearance quite a bit without touching my markup. I think we can and in many cases must keep them separate. And in the process, make the web better for those who need alternate presentation of the sites they browse.
