1. Isn't mentoring more of a long-term thing, where you interact regularly and the mentor is invested in some way in your success? To me it looks more like one-off advice, maybe this could be called "micro-consulting".
2. How do you ensure the quality of the replies? For example, I can imagine mentors giving canned responses without going into the specifics of your individual case.
3. Kind of in the same vein, do you provide pointers for asking a good question? Asking good questions is an art in itself, I can imagine it's difficult for a lot of people and greatly influences the quality of the reply.
