I believe some questions are very much country-specific. For example, there are quite some differences between the usual PhD programmes in the US and the UK and I have spent some time trying to think of an answer before somehow inferring that the question refers to something I wouldn't know about.
I don't see this as a problem as such (after all, academia is very international and people move between continents all the time), but I would like to have a way of pointing out to the reader whether the question is (potentially) country-specific or not. Otherwise there will/might be answers that don't apply to the question at all, and readers can happily skip the ones that they won't be able to answer.
I think there should be a tag/tags or at least a convention for questions to point out the country in the same way as people generally point out their particular discipline.
Any opinions on that?
