An edit to this question suggests that we have a tag for Poland. Is it a good idea to have location-specific tags? I'm guessing that most of the content on here is based in the US, should we have a "United States" tag, which would then (potentially) run rampant? UK is also very popular, I surmise. Poland kind of makes sense, but only in that it's a "destination" for most of the user-based; would Polish users asking questions about an American beer then tag "United States"?
(I could ask about the granularity as well -- country vs. state / province, etc, but I suspect that's a good enough sub-question once this is resolved.)
