      Okay, who's gone and changed the Wiki page for "Quantity"??
      "property" is not a link but "magnitude" is, which gives a loop.
      (Quantity->Magnitude->Ordering->Mathematics->Quantity).
      I know it worked *before* I started reading these comments (around
      12:30pm Eastern)

    Okay.  It's back now.  Loop gone.  (And I did try refresh a number of
    times.)

  Aha!  It all makes a lot more sense if you look at the
  revision history for the Quantity page.

This is the way the Wikipedia ends.  Not with determined vandals, but
with bored hackers.
