NY-based Betaworks has acquired and relaunched hownow, the iOS app hyper-local social network. The app enables semi-anonymous conversations at various levels of proximity such as “block,” “neighborhood,” “city,” or “worldwide.” The app allows messages to be set to expire over various time periods and was most widely used by demonstrators during the recent “Occupy movement.” The app was re-released last week on the App Store with the addition of Google Maps integration.
