But very rarely, I think and hope, do people come here to receive instruction, tutoring or mentoring. An internet forum would be a rather bizarre place to come look for that. It gives opinions that one can consider; thoughts that one can take up with one's instructor (if applicable) or consider for oneself, whichever applies; suggested facts that one can look up in the relevant publications. Occasionally, information that is non-critical or trivial enough that one can afford to take it at face value. But mentoring, at an internet forum? Hardly!
Rubbish.
People ask questions here all the time. It is very rare they dont get the correct answer - assuming there is one.
The problem, I would agree is sometimes sorting out the correct answer from those who dont know what they are talking about. However, even that can usually be deduced.
I have learnt as much about flying here by trying out some of the answers as anywhere.
That said, obvioulsy the forum will not teach you how to fly an aero routine or an IAP - it tends to be a bit more specific than that.
