Taking WebmasterWorld as an example, the Edit Skin facility was helpful to me, and I'm glad it's there. I customised the way that WebmasterWorld looks to me, to suit my monitor/eyes etc.
But I wouldn't bother doing it unless you have a *lot* of repeat visitors.
I'm not sure how Brett did that here, but I would think the simplest way, given that browsers will cache a CSS file, would be to create the CSS file on the fly with the users parameters based on setting a cookie.
