In case you missed it, there's a new close reason:
Seeking personal advice. Questions about choosing a course, academic program, career path, etc. are off-topic. Such questions should be directed to those employed by the institution in question, or other qualified individuals who know your specific circumstances.
I realize this close reason was created specifically to deter academic advising questions. But the wording is more general than that. In particular, can I use this close reason to close any question that seems to be asking for personal advice, unlikely to be useful to anyone in the future?
I'm thinking in particular about questions like Failed Calc 2, Next step to learn mathematics for a high school student, and a significant other number of the questions under the advice tag. Some questions are supposedly about specific textbooks, which might be okay, but they still read like personal advice (see this and this). These do not seem to be of great quality or wide applicability to me.
Yet, not all personal advice questions should be closed, else we should get rid of advice altogether. And there are certainly on-topic advice questions: Can I use my powers for good (even if it does have some personal detail, it's pretty generally applicable), and others.
So: under what conditions should I vote to close something as "seeking personal advice"?
