Some questions are inherently quite localised. For instance How important is a grade point average on a resume? makes little sense to those of us outside of the united-states.
I don't think questions like this should be closed as too localised, since they could be of interest to a large number of stack-exchange users, but I think that the rest of us being able to filter out such questions would be of use too.
Personal Finance and Money has country specific tags, which work very well, yet there are still plenty of questions which are not country specific.
