I'm definitely being influenced by books, and I'm not sure whether it's a good thing or not.
You know how sometimes in technical books there'll be a sidebar, or a little inset bit of text or something similar, indicating either "This may be interesting but not crucial" or "This is absolutely fundamental" depending on any icons that go next to it? Usually they have a different background colour, so clarify their bounds.
Well, for the first time I've found myself doing it on SO. In this answer about floating point a comment indicated somewhere that I wasn't being entirely clear — or at least he brought up a somewhat separate point.
I wanted to address that point, but without losing the main train of thought... so I (ab)used quoting to get the same sort of effect I'd try to achieve in a book.
So, my question is: should I actually introduce it in a completely separate section, and not try to turn SO into a book? Or is this a handy way to use markdown? I'm certainly not quoting anyone, so in those semantic terms it's wrong....
I care a fair amount about the presentation of my answers, so I'd be very grateful to get feedback on alternative approaches before I go too far down the road and start getting used to them.
