This document discusses city-specific top-level domains (TLDs) like .nyc and how they can be used to create a "digital civic commons" for a city. It notes that over 30 cities now have their own TLD and .nyc has issued over 86,000 domain names. The document advocates for a bottom-up, multistakeholder approach to planning how a city's digital commons could provide resources like neighborhood directories or civic issue forums through domains like neighborhoods.nyc or issues.nyc to help organize and share a city's digital identity and assets.
