At CloudMade we have been doing a lot of research and comparison into 
the quality and completeness of the map but more focussing on Europe and 
the USA. So it is very interesting to see this and see just how far 
ahead we seem to be in less developed areas.

I would be very interested in looking through that spreadsheet Alex, 
could you send it over to me. Perhaps I will go through the list myself 
and do some rankings and we can compare results.
