Yea. It's one of the things that's an improvement over the old site.
I like black text on a white background. Think NY Times, Wash Post, Google News, etc. They're on to something. OTOH, I can't bear to read TGR - it's visually offensive (probably intentional, but it keeps me away from a board that I might read otherwise.)
Note that the old site had a feature where you could pick your stylesheets and "customize" the look of the site. That shouldn't be too hard to implement on the new version. You want orange text on a blue background? Knock yourself out.
