Home tweet Home: Twitter Chooses the City Over Sprawl by Sarah Goodyear, Grist, April 29, 2011. I spent the last couple of days at a conference about climate, cities, and behavior. One topic that kept coming up among the municipal officials there -- from places like New York, Denver, Vancouver, Richmond, and San Francisco -- was the importance of walkable downtowns to attracting business and investment. Amenities like good transit, bike infrastructure, and dynamic public spaces are increasingly being seen not as frivolities, but as essential tools in building a city's economy.
