Leading questions are good, I don't advocate people just telling the answer directly and I follow your approach in terms of leading questions. From the examples you give I would suggest you aren't the kind of sanctimonious pick that I was trying to describe.

The example I was giving and probably not stating clearly enough, was of a member, who on a number of occasions has approached other team members and asked questions out of context like an on the spot quiz.

As an aside to my first post it's also interesting to see the people that will openly admit whether they have messed up.

Anecdotally it is usually the people who are less willing to share their knowledge that will try and shift the blame.

BTW, I am revoking your sanctimonious prick status....
