This forum is an American forum. The startup accelerator behind it is American. Facebook, Google, Amazon, Apple, Microsoft, the world's largest software companies are American. The next largest country for software would be China, which is probably more then the entire continent of Europe, but we're not communicating in Chinese right now are we? The majority of top computer science programs are based in the U.S., with 1 or 2 outliers from China, the UK, and maybe Singapore. Tech talent tend to aggregate around those tech hubs, and it should be obvious from context that it's not Houston, Scotland with a population of 6,000. Seattle is derived from a native American word, there should be no ambiguity that it's American. Do you expect people to specify that Los Angeles, San Francisco, and New York are in the United States every time?
