Eric is a smart guy but the CSS stuff is a crock! As is clean code results in higher ranking. I used to code by hand and validate. Stopped and there was no change at all in the rankings! If it helps it definitely doesn't come under "sustainable competitive advantage" which is what real marketers seek! Those who stoop to selling perceptions and what they do are the ones who see it as a competitive advantage! As to using CSS, I was bringing content to the top using tables in 96 and continue to do it today. CSS is wonky technology that has never worked as expected. All it does is waste time and pad design bills! It's great for formatting display the rest is iffy at best and using it for positioning is and always will be an exercise that causes a lot of frustration!
