The reality, which I myself have only very recently come to accept, largely but not wholly as a result of my experiences at CCMF, is that you cannot know what you really want until you have had a chance to test drive the product.
I do not consider myself a fool for not anticipating that electronic publishing of statistics would liberate the publisher from the tyranny of latecomers. It is not by accident that the things we do with computers resemble the things we used to do before we had computers. No matter how inventive we are, our imaginations are bounded ultimately by what we know.
