I would cite as an example of "too localized" the following question: 

[Suggestions for mathematics courses that would be essential for research in homological algebra and ring theory](http://academia.stackexchange.com/questions/381/suggestions-for-mathematics-courses-that-would-be-essential-for-research-in-homo)

The original post asks for information on what courses to take for a specific concentration within a specific program in a specific university drawn from the same school's course catalog. That would definitely fall under "too localized" rubric, in my opinion.
