If we still want to explore dynamically loading article sections (which we all seemed to be in favor of when we did annual planning back in June), it's hard for me to imagine how we could realistically pull that off if we display sections uncollapsed as default.

We could rig up an "infinite scroll" type of situation, where we basically:

* load section 0 and section 1

* leave placeholder <div>s for sections 2 and beyond

* when the user scrolls down into section 1, start loading section 2 in the background

** prepare the same thing for the bottom of section 2 load section 3, etc...

Of course a problem with this setup is that if you go offline partway through reading the article, the later sections might be unavailable when you scroll down to them.
