The Answers Corporation announced that its WikiAnswers social knowledge Q&A community reached four million questions only 72 days after reaching the 3 million milestone. The 4 millionth question was:

• Are there any new sports in the 2008 Beijing Olympics?

The question was answered and placed into the Beijing Olympics category by members of the WikiAnswers community, a group of over one million registered users and over 350 volunteer supervisors from every corner of the globe.
