Right now I write my answers sort of like essays: the answer has a thesis, generally present somewhere in the first text block, and the most answer-y portions of the answer occur in the first and last (excepting a footnote style addendum, when present) text blocks, while the middle passages serve to explain and support each aspect of the answer.
Recently I was made aware that having critical information succinctly stated only in the last paragraph makes it less likely to be read, resulting in it seeming 'hidden'. It occurred to me that I could instead put information in descending order of importance, like a newspaper article, on the assumption people are only going to skim the answer.
Are either of these options expressly encouraged or discouraged by this site or SE policy? Is one generally better than the other or are they both good, but in different contexts (and what differentiates the relevant contexts)?
