I have added two buttons on top of the right sidebar to toggle the blog's colors. I hope this helps. The toggle setting is saved via cookie; future pages should turn white automatically until un-toggled, though they'll load in black (not sure how to fix this).
Those who like the original white-on-black color scheme will see very little difference, though if this template change has broken anything on your browser (I've only tested Firefox) please tell me.
Oh, yes... more content? I'm working on that too.
UPDATE (6/3): Also added a shortcut icon to the site.
