So, you heard someone use the phrase, a picture popped jumped into your mind, and you were sufficiently confident that the picture in your mind was accurate that you started using the phrase yourself, accordingly? I suppose if everybody did the same thing, you might get "widespread acceptance" of a "widely understood" term that was, in fact, completely wrong. "While the unit costs of the new technology may initially be higher than that of the pre-existing one, due to the presence of a learning curve the unit cost for the former may eventually become lower. However, in deciding whether to switch to the new technology, a manager in a firm may be uncertain about the slope of the learning curve: if the slope is very flat, it may be worthwhile to maintain the old technology, while if unit costs decrease very rapidly it would be better to switch to the new one." "Learning About the Learning Curve" (http://bucky.stanford.edu/cef97/abstracts/bala.html) It seems that the professionals (i.e. "eggheads") use flat slope (i.e. "shallow learning curve") to refer to a difficult-to-learn task, and steep slope (i.e. "steep learning curve") to refer to an easy-to-learn task. -Michael Robinson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
