Anyway, there is another discussion to be had about whether Scotland should secede. Charlie Stross tries to draw some conclusions about the general desirability of small states here; I show incredulity and confusion about his argument here and here.
Sadly, Charlie has disabled Livejournal commenting, but I would encourage more participation, if only to help me understand what it is exactly that he is arguing.
