Context: On the web, sections are collapsed by default. On apps they are not. Assuming that one treatment was better and wanting all platforms to benefit from it, we did some research. Tilman did some analysis that suggested people read more when the sections are not collapsed. The question is, do people like it more? Does anybody have any major problems with it.

Questions: Across reading use cases (overview, quick lookup, deep learning)

• Do readers prefer collapsed sections or uncollapsed?
• Do readers read more if sections are collapsed or uncollapsed?
• Does either treatment cause specific problems for readers?

Note: the above comes from @JKatzWMF and is subject to modification for testing. This ticket is for the initial planning phase of this project.
