I am a long-time contributor to OSM in Germany and elsewhere. I have worked on a lot of different OSM software. I’m also a regular OSM conference visitor, having participated in all but one of our “State of the Map” conferences and lots of other events. I co-founded Geofabrik, a small OSM consultancy in Karslruhe.
When people come to OpenStreetMap for the first time, their expectations are sometimes at odds with what the OpenStreetMap community is doing. If you have been puzzled by an OSMer telling you that OpenStreetMap is not a map, that openstreetmap.org is not aiming to compete with Google Maps, or by their stubborn refusal to remove a private trail from the map, then this talk is for you. It will explain the basic tenets of the OpenStreetMap community and how they apply in practice.
