Here's a hypothetical.
You work in an office where everyone has access to google and any non-porn website. You're tasked with finding interesting trivia questions on a daily basis. Each day, you send out a trivia question which becomes a race to see who can google the fastest rather than an actual test of knowledge.
Where would you turn for interesting trivia questions which cannot be googled?
Math puzzles and personal information about one another is no interesting.
