OK, I see your point that it is important to develop software by building prototypes and throwing them away if they are no good. On the other hand, I think it is also important that we do not release software to end-users until we are reasonably sure that the specs won't change. End-users are hit hard by incompatible changes. As always, we need to find a middle-of-the-road compromise. How about trying to spec it out as much as possible, and then implementing a few prototypes without letting end-users get their hands on them? - -- EvdP
