Following on the question What's the policy regarding localized (read: country specific) questions? and Are US-specific questions OK? My own opinion is that country specific questions are fine. But, I think that even if the OP is asking about their home turf, there should be space to provide general answers. Since this site is inclusive I think the Q-A should be made general if there are general interest in the question as such.
An example: the post How much vacation time is typical during a PhD( in the United States)? (the parenthesis indicates an addition edit to the original question indicates a problem. As indicated the post was a general question applicable everywhere although it was clear from the question body that US conditions were at the heart of the OP. The question was later edited to show its US identity.
The edit now makes the question very narrow and opens up for questions about vacation in each and every country. This is really not constructive and what we want. On the other hand I can see that a non-country-specific question would open up for answers from each country, in other words wiki-type posts. However, when somebody looks for a question on vacation having the question, in my opinion unnecessarily, limited makes little sense. I think that providing a wide spread of answers to a more general question is the better way. I realize this is probably not easy to resolve but as I see it: should we try to be very specific and excluding or try to be general and including in the these types of posts?
