See, this is a bit I don't understand. If you have to zoom in then you 
can see if it's hi-res from the Bing images!

1. How many people map areas they've never been to. If they are, is that 
a benefit to OSM regarding accuracy.

2. If they're interested in an area why can't they just zoom in to find 
out if it's hi-res.

Sorry, but I think your time would be better spent get out & mapping

The blank areas have hi-res imagery (caveat: I have checked every tile)
