Treat: The great "pop" vs. "soda" controversy. It's "soda" here in Philly, as this research paper's demographic map shows. If you submit the stats on what you call it, and where you grew up learning to speak this way, you get an option to see the total stats. Amazingly, "pop" leads (as of today), which has to be falsified research data (or for whatever reason, this site gets inordinate hit numbers from the flyover states).
