Another way to make the reading experience much better would be to not use the color black. This article explains pretty well why you should never use this color. http://ianstormtaylor.com/design-tip-never-use-black/
For the ebook reader on the main page at magicscroll.net you can set it to use Ethan Schoonover's solarized colors: http://ethanschoonover.com/solarized which I prefer to the black on white.
