Or if you're like me and find all the white backgrounds hurt your eyes, its simple to enforce black background / green text which makes reading much easier on the eyes, it also makes grey text easier to read.

This is a neat idea but it's no good for me because I read HN from several places and I don't want to manually create a user style sheet in each one.

Thanks for the tip.

Does anyone have good designs that stray from the general HN look?
