I've been using YUI Grids for a couple of years and it simplified my CSS. I use it to "reset" all the default rules for the browsers so that things like font sizes and spacing appears uniform between the browsers. Then I use it to set up an initial grid layout for the base columns and rows of the site. I moved from YUI to jQuery because I wanted to use a lighter framework, but I've continued to use YUI CSS because it's still pretty tight. However, I hope that YUI does look into add compatibility for HTML5 tags because that is something that is lacking.
