Imagine if we engineered all things in real life by first expending effort publishing all the ways not to engineer them. That would be a good way to insure that nothing would ever get engineered. It would *stifle* all or most production. In mailing lists I have observed there are usually a few key guys who are sort of like the local bullies on the neighborhood street corner. Their whole purpose in life is stifle any other boy from coming into the neighborhood and "stealing" (e.g. giving more opportunity to) the local girls. Luckily they tend to not be very smart, else they wouldn't be wasting their time sitting around the local neighborhood.
