This is rich - on the AdWords Help page for Optimizing Ad Text [adwords.google.com...] it still says this:

Use capitalization to your advantage. Capitalize the first letter of every word in your display URL to bring more attention to your company name and brand. For example, www.CheapTireShop.com will encourage brand recognition much better than www.cheaptireshop.com. Ads that use intercapitalization can also look more professional.

Good goin', Google.

(hat tip to @Dr_Pete for finding this)
