great find. absolutely fascinating observation on social dynamics in a small space. i found the physical features that affect the interaction to be particularly interesting (about 7:00 in).
"What physical features make space work?" is a very interesting question indeed. It is at the core of research by Christopher Alexander, especially "A Pattern Language" - the book that inspired the pattern movement in software design.
Today I walked to the top of Mount Royal in Montreal. It doesn't quite qualify because its about three miles in length, but it does qualify in that its a road (snow/ice covered today) about 20 feet wide. I found it fascinating - the mix of tourists/locals/dogs/snowboarders/ in the middle of a city.
