It appears the site now offers a dark theme by default. Scroll to the bottom and you'll see 'classic blue' - click that to give you dark theme. Useful for mobile where I can't use stylish.
But it's nowhere near as nice/easy on the eyes, with too many contrasting harsh-contrast elements. It's like a sexy goth girl, you can't help but accept it, but that doesn't mean she's not eyesore.
Comparison:
Agreed, but for mobile users it's better than nothing! I really don't like the orange though on that theme.

There is an alternative for mobile users, under your username -> preferences, scroll down and there is a "Custom CSS" field. I seem to think this was mentioned briefly and should do what you want.
Same on mobile!
