I am writing a review/tutorial paper in the field of computer science. Review articles in the journal where I want to publish tend to be long, with in-depth explanations. Now I'm in my third section of the article and I am not sure where to put a signpost paragraph. I can either:
Start a new section with it, the rationale being that a reader gets to know what is in this section straight away.
Put it after 2-3 paragraphs, so the reader gets to "taste" what the section is about and then can decide it he wants to continue reading for in-depth explanation or go to next section that might be more interesting for him. I would prefer this option, but then the signpost paragraph interrupts the flow of ideas that was started with the first paragraphs.
The journal's guide of style has nothing about signpost paragraphs. Reading other articles, I noticed both usages and would like to know what others think.
