We've seen this data set before, but not in quiz form.
Really? I've taken similar quizess probably a dozen times or more.
These sorts of dialect maps, and assertions about who says "soda" and who says "pop" always annoy me for some reason. For one thing, they often get over-generalized, to the point where people will say "oh, you're from the South? You must call everything "Coke!""
Nobody, and I mean NOBODY, I knew growing up on the gulf coast of Florida called things "Coke" unless it was actual Coca-Cola, or at the very least, a half-decent knockoff brand. The only kid I knew who called it "pop" had moved from New York. I heard "soda pop" from a few, but not as common as "soft drinks" or "soda". To my grandma, it was "cold drinks."
Florida is not a monoculture. Very broadly, areas of northern and central Florida share more culturally with "the South" while the coast is more Midwestern-ish, except areas of the keys and west coast which are kind of their own thing. And "the South" itself is not a monoculture either; there are places in Georgia, Tennessee, Alabama and Mississippi which have their own distinct accents -- sometimes half indecipherable even if you're from somewhere else in the same state.
Anyway. This quiz decided I was either from North Florida or Raleigh -- and it also highlighted parts of New England and Colorado. Nope. Bradenton, and I've been living in St. Louis for 15 years (and aside from a couple of vowel sounds from people who've lived here for a long time, those dialects are pretty close to identical).
