That there are no dumb questions is an appropriate model for children. Such an approach is not workable elsewhere. Everyone's time is valuable. It is each of our responsibility to pay attention and think for ourselves and not waste each other's time.

TRUE!
But we do have the choice if we think a question is foolish or a thread is not interesting to pass on by!
May you have A Healthy and Happy New Years!
