Webmonkey talk OSM

Unlike some crowdsourced projects that have fizzled, OSM has managed to attract a large following of enthusiastic contributors who constantly “trace” routes they take by car, bike or foot. Users tag points on their routes, and share the resulting places of personal interest on the maps with other users. Some of the bigger map providers also offer such geo-tagged metadata, like Google’s MyMaps.
