I post a trivia question every weekday (or so), along with other interesting news in the world of Trivia (contests, games, etc). When the next question goes up, I go back and add the answer to the previous question. The answer will be "hidden" - you'll need to highlight the text after "UPDATE: Answer" to see it.
The questions are probably all google-able, so you're on the honor system. Try to answer them off the top of your head. Post your guess in the comments. First correct guess gets all the glory. Feel free to mock everyone else. Heck, feel free to mock me for the lame question. :)
Email me at mitch42(AT)ghostowl.net if you have any suggestions for the site, complaints about a question, or just to say "hi!".
