I've noticed a trend in discussion databases. Someone posts a question. The first few responses are often of the form: you should have asked the question in this other place, you should have searched this database because the answer is here already, or you really should be asking this other question instead.
Most of these responses are from those who know the answer, but instead of just answering, they don't include the answer, in seeming punishment for asking the question. Those who answer with the you should have searched this database response must have actually done the search to be able to say that - yet all too often the link to the answer is not included.
This is creating a culture where it isn't safe to ask questions.... Whatever happened to the "there are no dumb questions" attitude?
