I am convinced they have monkeys for designers. WHY on earth would you allow "About 30,2000,000 results (0.25 seconds)" to take up space?! Are these guys insane? That's the most useless information on the page, and it's pushing the ads and search results further down.
Don't they supposedly use 8 million A/B tests for every little design tweak?
And they do this because we're in a "Post Steve Jobs" era where every designer wants to be a Prima-Dona Jobs-successor Rockstar Diva who re-invisions all the company's products. You'd be surprised at the illogical changes and constant redesigns they make with YouTube and Google Analytics. I'm actually moving away from G-Analytics to Piwki because of the obnoxious "anti-middle-click" interface. With YouTube, Jesus... They change something every week. At least on my account they do.
