Here's some fun (via Andrew Sullivan). It's Google Trends. You can put in 'cricket', for example, to see which cities and regions searches are mainly coming from, and in which languages. This is what 'geras' gets you. And this is the result for 'Emmylou Harris'. Now what happens if you put in 'Chomsky'? Guess before you look. What city? What region? Here's the answer.
You might also like to try Googlefight, in which you can stage one between any two items you like. For example. (Thanks: JG / StM.)
