Recently in another thread, the question of "Guides or No Guides, and Why?" came up, and one proponent said that guides could be very useful for setting up scares, and so on, and that they can work. Other conventional wisdom says "not".
PS - I was tempted to make this into a poll, but I think that it would either be surprisingly split, or not surprisingly one-sided, ergo, no real value in a poll. Better to just discuss it's merits (or lack thereof).
