I, personally, am a fan of the time between posts being more fluid and not having a concrete "there is always X amount of time between post 1 and post 2".
Works for me. And hey, Ulthein could've been destroyed and the Dwarves just said "fuck it, we'll build a new capital and name it Ulthein too".
EDIT: AAAAAARGH; @Frengo, could you put the blank NS on the first page or something? I have looked and looked and I just cannot find where you posted it before.
