Why do educators always fail to effectively communicate with a non-captive audience? The author needs to re-work this so that the first paragraph tells me everything that I need to know, and the rest of the essay/letter/memo can elaborate on things that I should or might want to know. If they aren't willing to do that then they are going to continue to remain out of touch to most people.
