Indeed, as with my earlier link (http://subtraction.com/pics/0703/grids_are_good.pdf), I'm not arguing against grids as a design tool. I'm arguing against transferring them programatically to HTML and CSS when tools like http://hashgrid.com/ allows you to transfer them visually just fine.
People argue they need grids for their websites to be responsive, but that is not what grids are for. At least not according to Massimo Vignelli.
