Arthur Jay Klinghoffer, a professor of political science at Rutgers University, has argued that geography seems less relevant than ever in a world where nonstate actors -- malleable entities like ethnicities, for example -- are as powerful and important as the ones with governments and borders. Where on a map can you point to al-Qaeda? Or Google, or Wal-Mart? Everywhere and nowhere.

During the whole 'Jeopardy' experience, I felt like I was living a bit of a double life, I would be secretly flying out to L.A. to tape new shows, hoping that none of my coworkers would notice the absence and figure out what was going on. 'Jeopardy' tries very hard to keep their secrets.

I threw the opening pitch at a Blue Jays game, and after the pitch, the mascot asked me if I wanted him to sign the game ball, which I thought was funny. What would he write? "Best Wishes, Some Guy in a Bird Suit"?"

For some reason the most devoted mapheads seem to be kids.

People are using GPS systems to find millions of little hidden objects throughout the world - often as simple as a piece of Tupperware hidden in the woods. You go to a website, you get the latitude and longitude to get the specific location of a certain specific hiding space, and then you go there and see if you can find it.

It's boring to have the same guy win. I'm actively rooting against myself.

There’s just something hypnotic about maps.
