Google Maps Local Guide is one of the tools being used. For example...Take a look at this special pizza map below. Kaliko Beach Club Haiti is pinned as are multiple pizza joints et al. The Map traffics the Florida region. Have a read over the reviews and pay special attention to the photos in the 'guide's' album. Mappers can answer questions, pin and name locations as they wish and edit and delete as they go.
