Really? I see this sentiment often and it's baffling. If anything OpenStreetMap shouldn't have even allowed on the ground edits in areas with good unencumbered data before the basics were imported (TIGER and NHD in the US). It would take decades to get any sort of a meaningful map in the US without the TIGER import. Sure, the high population density areas will get mapped well and quickly, but not the low density areas.

Not just "less good" but straight into "bad." I mostly agree. But some of these problems will be less of an issue as revert and merge tools become more mature. On the ground mapping is the best, but at some point falling back on less accurate data seems better than no data. -Tyler
