Almost completely OT: It's been a while since I did not enter twitter's landing page. Why is there an ugly brown background, or the too-much-intense-that-hurts blue? The pictures, I understand, they tell a story. But the background color has no excuse. There should exist a more pleasant tone. Is it just me?
