For some reason, google has stopped serving ads to our main page, and instead is only showing public service announcements. Oddly enough, if we add anything extra to the URL, i.e., "whatmillion.com?do_nothing," it works fine. We think this is because google crawls on the fly when it sees the "?", but has a stale default cache for the main page.

To fix this, we followed google's instructions to create a "collapsing ad unit," so the ad just goes away instead of displaying those annoying hurricane messages.

Secondly, on submit of a currency value, we append a random word to the URL (unless one of the 'hidden modes' is being used), i.e. "whatmillion.com?peace" or "whatmillion?luck".
