This book is a must-have for any architect, urban designer, sociologist, or anyone interested in how people work, how places work, or how people and places work together. I flew through this book faster than any book I've read in the last five years; it is an absolute joy to read. Whyte's sense of humor is so much fun and his extensive research drives home the points he is trying to make. Whyte's research is fascinating, from human personalities to human interaction, and from physical street design to the amenities that make spaces lively. No matter what you do for a living or what you enjoy, I think there's a small part in everyone that is intrigued by people and how we operate, and I also believe that there is a part of everyone who is interested in designing things. This book gets down to business right from the start at identifying these things that pique our interest and explaining them in great detail, in a plain-language, easy to read way. You will be hard-pressed to find a book - in any genre - where so much genuine and relevant research is so simply and clearly explained. Just buy it. If you're on the fence, just get it. You won't regret it.
