Paper of the future

OK, has anyone else noticed that most of the paper--including books--in BSG is cut to have diagonal corners? Why? Is there some major need for tiny triangles of paper, and so it makes sense to send every sheet, big or small, through a die-cutter? Because, unless they've discovered a new way of making paper in the future, I can't see how it would conserve resources, which you'd think they'd be especially conscious of what with being in a convoy, always on the run. But maybe not. Maybe paper's so ubiquitous they just cut it up for fun.
