Thoughts on Google's "A Google A Day"

Time for something different! Today I discovered "A Google A Day" (link currently not working properly), where Google posts a strange trivia question and challenges you to use your Google skills to find the answer. To make it so that you don't get spoilers for your question, the Google engine used for these trivia questions is based on the state of the internet the day before the question comes up (unfortunately spoilers for old questions can and will get through), which I think is a brilliant solution to the problem. I had a ton of fun going through the two months worth of questions currently available, but throughout the experience I had one persistent thought.
