What does it mean for a city to be connected? And is there quality resulting from this property? Let's define the basic node of a city as a doorway. (Not necessarily a building. A single building can have many doorways to separate spaces.) A connection is the distance from this doorway to the next node, that is to say the next doorway. A well connected city is a city where the distance from doorway to doorway is minimized, since everything will be easily accessible from the public space.
I will, but not very often. After something grows big, there comes to be a point where you contribute more by removing things than by adding more.
