<http://wiki.openstreetmap.org/wiki/Import/Catalogue>You can download the
planet and filter those out, and you will have weeded out most of the
non-human-contributer data. 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.
