I can't think of any US, national-level imports (other than the original
TIGER import, perhaps) that have gone well. I know because I started or
performed several of them: county borders, NHD, etc. Local-level imports of
data from counties or states are quite a bit easier to deal with, so I'm
proposing we work on getting this national-level one closer to correct.

In the areas I've spot-checked, TIGER 2010 has better resolution and more
road data than untouched TIGER-imported OSM data. I have yet to spot-check
areas that have been edited by OSM members.
