Yes. I do enjoy answering questions that would let me share personal experiences. Other than the fact that these questions are way easier to answer than those requiring technical knowledge, the way we write our response would be very different--it's just as if we're telling a story to a friend! Moreover, in doing so, other people may pick something up from our experience, especially when we are deemed more experienced on the subject at hand that the 'questioner'. They'd be able to weigh their options better, as we are somehow providing them a glimpse of the other side of the coin.
Apart from that, we may also impart them the realizations that we have come to arrive at after going through such experience. And if they are to choose the same path that we have taken, then they'd be more comfortable to do so, as we, ourselves, have been the living proof that every experience, good or bad, holds within it a lesson of some kind.
