The New York Times recently published a 25 question personal dialect quiz developed by their graphics editor, Josh Katz. Based on your answers, 3 maps are generated that predict where in the US you are from. I found some of the questions to be interesting, and my results were not surprising: the map predicted I was from Philadelphia (true story!) and Massachusetts (which is where my mother is from).
I would love to hear how your results compare. You can find the quiz on the New York Times here.
