Minimum Page comes from a frustration with CSS resets and bases. Ripping down the styling only to rebuild many of the same styles is unnecessary, especially for defaults common to all browsers.
To encourage people to consider the code they insert in their site, the styles aren’t provided in a minimised form. Developers should edit the original base to make generic, site wide changes.
It’s exactly what we use to start all of our CSS at Soupgiant. We think it’s important to share.
