 Personally I'm starting to use multipolygons more and more - define a
"boundary" once and reuse is as many times as needed by the landuses
either side.

    I'm kind of considering if this is right or not - if a road is
    the divider between two landuses, is it still best to unglue it
    from the landuse(s) and move it into one or the other?
     

  It's best to unglue but it's also not wrong to glue the landuse. Some
  will say it's inaccurate, but hey, drawing a road with a polyline is
  also inaccurate.
  In some cases, ungluing can be worst : imagine two parallel streets
  and one pedestrian square in between. If you unglue the square, you
  need polylines to represent the roads connection (for e.g. pedestrian
  routing). These lines are inacurate because they can be drawn at some
  intervals only where physically the connection is everywhere along
  the square. If you glue the pedestrian square, your problem is easily
  solved and closer to the reality.
