Most trends are fleeting, some of them mercifully so. Some last no longer than a Lady Gaga wardrobe change. But urbanism is still, by and large, a leisurely exercise, so it's no wonder that planners still embrace fashions on a nearly generational basis. It often takes that long just to see if something works. Or not.
So, while Gaga would inspire us to attach telephones to our heads and light our bustiers on fire, planners who ascribe to the principles of smart growth are still rhetorically swaddling cities in the urban equivalent of flannel. For better or worse, this age may finally be coming to a close. Don't cry, Monster.
