I confess to not fully understanding all the statistics in the article, but it is clear that "casual" mappers make significant contributions to OSM. I did wonder about the statement "... about 500 users in the core group of the OSM are highly networked in terms of collaboration." Really, collaboration? Someone just made a mass edit in an area I watch with a user name I didn't recognize. Nothing wrong with the edit, I'm just pointing out that we don't always collaborate. Imports are a good example of when we do and a perfect example of when we don't. Clifford -- @osm_seattle osm_seattle.snowandsnow.us OpenStreetMap: Maps with a human touch
