Random tangent: This is the most bizarre thing I've seen in a while. At the bottom of the page is a "Protected by Recaptcha" logo that follows the page around. Clicking on it does nothing and no Recaptcha is displayed. What is it supposedly protecting and how is it doing that protecting if no Captcha is displayed? (I browse privately and am constantly hit with Captchas, but this one didn't prompt me.)
