To me, “IE9 is the IE6 of CSS3” means exactly what the article illustrates: “You will be unable to deploy cross-browser sites using exclusively CSS techniques like CSS gradients and text-shadows without fallbacks specially crafted for one browser.” IE9 will be holding CSS3 back from meaningful adoption and impact. Others here are griping the author could have done more to approximate the Webkit rendering in IE9. This is true but is counter-productive to the point of the article: Using only new CSS3 tools is impossible thanks to, well, IE9 being the IE6 of CSS3!
