I wonder how many software engineers, and how many of the GoF (Gang of Four) who wrote the software book that popularized patterns in the software world, actually read and thought about A Pattern Language. I'm sure some, but in my mind the subtitle "Towns, Buildings, Construction" examines patterns that are large in scope, medium in scope, and small in scope. One of my personal complaints about software patterns is that there are so few that are 'large scale'.
