Unreasonable demands on time: My biggest frustration with the professionals and most of the enthusiasts is that they are unwilling to produce advice in a form usable to the typical citizen. Granted, this is not easy to do. Over-simplify and the materials are "frothy" and "insulting." But the other extreme is the more common. Since e-prep is so important to the authors and the people selecting literature to distribute, they cannot conceptualize why normal people would not be willing to wade through voluminous documents.
