Downtown Is for People
Jane Jacobs has a somewhat ambiguous legacy—or at least one that's contested by different factions in the present-day debate over cities and urbanism—but to me her most important idea is encapsulated in the title and spirit of this piece. It's old and, I think, utterly prescient about what successive waves of planning fads miss. The purpose of urban space is for people to use it. A great place is a place where people want to be.
