Certainly, I hear more often from people I talk to that one of their big
gripes with the mobile site is inability to use find in page when sections
are collapsed. I know at least 3 people who open all sections just to use
this function. Maybe I'm missing something, but based on your results it
seems we should be moving towards expanded sections by default as soon as
possible. There certainly doesn't seem anything negative here. If not what
would you suggest as next steps before doing that.
* Readers in the test group (sections expanded) tend
to stay longer on
This seems like a good result to me.
* Readers in the test group tend to spend more time reading, and less
Again this seems a good result for sections expanded.
I'm not entirely
sure what you mean by less time navigating though - is this
to another page or to another section (the latter seems a given if sections
are already expanded)
* Readers in the test group tend to scroll more sections into view
than readers in the control group open
again this seems to be a good result.
* Readers in the test group tend to stay shorter on the page than
readers using the Android Wikipedia app (which offers a TOC for easier
navigation, something not yet available in the mobile web test group)
This doesn't seem like a fair comparison unless you compare readers outside
the test group to the Android app and talk about the delta.
