Steve Coast has worked in a variety of heavy lifting computing applications, from computational geometry to artificial life, and mapping applications. Steve lives in Denver, Colorado, and enjoys hangliding, Mongolian throat singing, and soccer.

As founder of OpenStreetMap, the free wiki world map, Steve undertakes a wide variety of roles within the project, from creating the API to his many public speaking appearances around the world. Steve is also chairman of the OpenStreetMap Foundation, a not-for-profit that supports and guides the project.

Richard Fairhurst is a journalist, cartographer, and programmer who has been involved with OpenStreetMap since the very first days of the project. He is best known for the Potlatch online map editor, but his favorite OSM activity is strapping a GPS to the handlebars of his trusty hybrid bike and going out to map a National Cycle Network route.

His day job is editing Waterways World magazine. In his spare time, as well as mapping, he is a volunteer Sustrans cycle ranger and plays the church organ. He lives in a small Oxfordshire town, which is reputed to have the highest concentration of OSM users anywhere in the world.
