The three Rs (Reading, wRiting and aRithmetic) were the education basics of generations past, but maybe now we should add a fourth, information Retrieval. We all turn to Web search engines like Bing and Google whenever we need to know something and the technology has revolutionized how we access and even think about information.

Google introduced A Google a Day as a daily puzzle to help you improve your search skills.

"A Google a Day is a new daily puzzle that can be solved using your creativity and clever search skills on Google. Questions will be posted every day on agoogleaday.com and printed on weekdays above the New York Times crossword puzzle. We’ll reveal each puzzle’s answer the next day in the Times and on agoogleaday.com, along with the search tips and features used to find it.

Just like traditional crossword puzzles, the difficulty of the questions increases over the course of the week, so by Thursday or Friday, even the most seasoned searcher may be stumped." (source)

Here's today's question:

With many people playing, you would expect to find lots of spoilers online as people comment on the daily puzzle on Twitter, Facebook or their blogs. To prevent this, Google's A Google a Day site uses a special interface that "excludes real-time updates and other things that are likely to include spoilers as people post the answers to the puzzle online."

Google is not the first company to think of using Web search games for marketing. Microsoft introduced Club Bing in 2007 to promote its new Bing search engine and now hosts a number of Web search related games on its site.
