Ai-ai-ai eyes!

Pet peeve: white text on a dark background. I just can't read it. Thirty seconds, max, and I'm going cross-eyed and blindly reaching for the "back" button. Why do people do this? Do they enjoy causing me pain? Why don't they just come over to my house and stick a hot poker in my eyeballs instead of luring me on with promises of thrilling repartee and then stabbing my eyeballs with white text on black background? I would rather rub sand in my eyes than try to read it.
