It would be an interesting excercise to render a map using only that data. Having said that, there's the important issue of human contributors adding value to the imports: adding metadata, removing stale data, improving geometry. Those are real human contributions that would not have occurred if it weren't for the import happening first. What would the US community / human contribution have looked like on OSM had we not seen the TIGER import? The Netherlands without the AND import? Questions without easy answers, but they deserve consideration if you want to consider what's 'true OSM' for you. -- Martijn van Exel http://about.me/mvexel
