As if the choice of green was innocuous. In the previous century, when I was a snobbish New Englander, Walmart was an unholy place--a store chocking the life out of small, friendly businesses and full of the kind of people that hindered social progress.
Now, as a snobby, academic Floridian, I take Rowan to Walmart for fun. And for cheap coffee (they sell the Starbucks for like 6 bucks).
Anyway, go watch FlowingData's map of Walmart's growth. Via ZeFrank.
