The document discusses how open-source mapping can benefit the navigation and location-based services industries. It summarizes MapQuest's investments in OpenStreetMap, including hiring contributors and hosting tools and services. While commercial data is still needed for some uses like navigation, open data is increasingly competitive for many applications. The author believes open data will not completely replace commercial data due to needs like ensuring roads are driven, but it will continue growing in importance. MapQuest is launching new open products like an SDK and aerial tiles to engage developers and further open mapping.
