Bill, I agree with your thoughts regarding the SS origins. However, with respect, my affinity towards Space Syntax is only because of your wonderful geometrical treatment/characterisation of open spaces, in much the same way, I like John Peponis and his group's work on convex-partition. These are simple and generally tractable ideas. On the other hand, I tend to take the results that show links between axial-line integration/depth/etc. and pedestrian counts with a "tablespoon" of salt. But, just like you, I long to see more advanced approaches, even though they may not show high correlation coefficient. Just a passing thought, I wonder if it would be worthwhile to make a nice graphic timeline of SS, to trace the lineages and branches. Sanjay.
