I think the responses on this board are usually just right for the questions asked.
People have different personalities and that is the way of the world. No one has ever been anything but helpful to me, when I ask a question.
Some of the responses can be "mean" but usually that is out of the frustration of the copy / paste homework assignment, with the added can someone program this for me.
This is a message board for programming so I don't see the need to dance around someone's feelings. But that being said, I don't think there is a need for someone to be flat out rude to a beginner question(Not that I really can think of an instance of that).
