It's not about whether the question is answered, it's about how applicable the question is to another person reading the question after the fact.
See What questions should be closed with reason "too localized"?
Note that this absolutely does allow for questions such as "the only martial arts around me are X and Y. What I want in a martial art is Z. What should I do?" The question, as discussed in meta.stackoverflow, is definitely localized. It's also definitely not too localized: other people are likely to face similar (or even nearly identical) situations, and would benefit from seeing the reasoning that comes with answers to that specific question.
For instance, the question that I think triggered this question was this. The OP has an option between karate and TKD. Do we know exactly what these schools do? No. But we can make a pretty good guess that the karate school doesn't wear judogis and spend 90% of their time on tai-otoshi, harai-goshi, and osotogari. We can give answers that are extremely useful not just to this person, but to the myriad other people who have a specific reason to diligently avoid concussions and are faced with the choice of not training, training in karate, and training in TKD. Most of making a good answer involves telling the OP what to ask, what to watch out for, and what to expect when they check out the school.
I think it's a localized question, but certainly not too localized.
