The sidebar takes up a considerable amount of space in the interface (if you are reading Wikipedia with a browser width of 1275px the sidebar takes up roughly ⅐ of the interface). Aside from language switching the links it contains are used by a small number of people (see general usage data below). In what ways does the presence of the sidebar affect the reading environment? If the majority of people aren't clicking on any of those links might it be considered clutter? Since it is used by a small number of people would it make sense to collapse/hide it for most people (e.g. logged-out users)? Which links in the sidebar are most used, and by whom? Would it make sense for the various sections of links within the sidebar to be collapsible themselves (accordion style)?
