The community does not owe him an explanation
Howeverm, merely posing a question, even with a suggested answer, is not a demand for an explanation. davidw doesn't make me feel like he thinks anyone here owes him an explanation. Also, reading this same question in many threads becomes a
bit annoying.
Which is an argument I agree with. On the other hand, the question is valid and warrants some discussion. Perhaps we need a meta-HN, where davidw could start a topic and we could discuss his actual question.
