(i.e. "tell them what you're going to tell them, tell them, tell them what you told them") That's what many subscribe to. There are schools of thought that disagree. Some readers enjoy not knowing where the text is going; done well, it makes the payoff significantly more pleasurable. What you said certainly does seem to be the fashion at the moment; the number of books whose first chapter is simply a dull forewarning of what each of the following chapters is going to be about certainly seems to have increased in recent years. I find it horrifically dull and generally skip that entirely. I see the same thing in presentations; it's just as dull (to me).
