Turned On the Lights!

We’ve gotten in touch with scientists who did some science and crunched some numbers to find that most people prefer the light to stumbling around in the dark. You’ll have to trust us on this one--the math’s pretty complex.

These two themes have been available since 2004, and we decided to enter 2010 with the light theme, while maintaining everyone’s ability to use the dark theme if that’s their preference. If you’ve ever used our handy theme selector icons on the right side of the masthead, you won’t notice any change. If you haven’t set this site option before, and you prefer the dark theme, just click on the icon with the dark background and the white “a” to make that switch.
