It certainly is a pity: a person may give some very enlightening
insight, but won't come back because of the arrogant comment
someone made to drive them away. There are other sites similar
to this one, and I hope they find better treatment there, and
enjoy their stay. This is not the private site of any of us, and
we need not rebuff anyone. There are lots of dead threads with
persons who contributed and who are no longer contributing.
And this could be a major reason why.
