Re: [Design] Stop collapsing sections by default

The more I think about it, the more I think, in its current state mobile should not collapse sections by default. If you really want to find a lower section, scrolling down the page and being able to collapse a section to see the next one is easy, yet if you just want to read the article in its entirety it is annoying to have to click to expand a section. Since we currently load all the HTML for the content of a page it seems silly to hide it (although we should certainly rethink this if we ever begin to lazy load sections) We ran event logging on toggling a while back [1] and the data showed as you got down the page, it was less likely a section would be toggled opened and read. I would propose we keep toggling enabled but change the default of all sections to be open rather than closed. This also removes the existing risk of a flash of unstyled content and enables the ability for users to do find on this page. We should at least run some kind of A/B test that rethinks this.
