The Betaville Massively Participatory online platform, launched at last year’s MAS Summit, is now hard at work: Projects are in the works or underway in Brooklyn, Manhattan,Istanbul, Copenhagen, Gdansk, Léogâne (Haiti), and Toronto, with an international consortium of researchers, developers, and advocates. Betaville is designed to provide a common language and medium for collaborative participation, a “place” where citizens, governments, and businesses can find common ground and creatively build consensus about specific changes to the urban fabric. The vision for the next stage of Betaville development, the City Research Studio, will be introduced.
