Want to play twenty questions? Play twenty questions against a computer. It can be startling good, sometimes, though there are a few things that still aren't in the database. Still, a decent time waster, if only for a little while.

20 unanswered questions about 9/11 - "Why after 730 days do we know so little about what really happened that day? No one knows where the alleged mastermind of the attack is, and none of his accomplices has been convicted of any crime. We're not even sure if the 19 people identified by the U.S. government as the suicide hijackers are really the right guys."
