This document discusses Zappos' Downtown Project which aims to invest $350 million to revitalize downtown Las Vegas. The project focuses on accelerating collisions, co-learning, and connectedness through initiatives like developing small businesses, tech startups, arts/culture, and real estate. The goal is to maximize long-term returns on community rather than short-term financial returns by promoting serendipity, learning, and innovation through density, diversity, and an active street culture.
