I was attempting to explain why many email products default to top posting and 'copy entire content' in replies. The intent is to encourage the inclusion of an entire thread in an email exchange to preclude an employee spending unnecessary time searching for the history of a thread in their mail storage. It is an issue of employee productivity. If this is still unclear I hope that someone else can clarify what I mean for you.
