Pull quotes are a feature of magazine typography which are often missing from web publishing tools - I often want to emphasise a certain thought/passage/etc in a way that provides a natural break in the flow of a piece of prose.
Any implementation of pull quotes should be careful not to break markdown rendering in things that aren’t writefreely/write.as - perhaps more <!--HTML comment fudgery-->
would be appropriate, much like we already use <!--more-->
?
