Yes, it does have appeal. Without being big-headed, it is always gratifying to have some special knowledge or skill that most others either do not have or would not recognise. Perhaps proficiency with a musical instrument that few know you have, let alone play. Even trivial things can be satisfying - like knowing exactly how to get from A to B by some devious road route or transport link that would leave anyone else floundering.
