Yahoo coverage is still very sparse. (And I have also never been able to
get it to work since I installed Firefox 3.5).
The surveying cost of collecting house numbers is an order of magnitude
greater than doing streets/pois and doing every house without satellite
coverage is another order of magnitude again as you have to collect
locations for every single house.
We can't really do polygons without satellite coverage.
So while I agree having every house is a desirable solution I think it
will be a very long time before this can be a reality other than in
satellite coverage areas, and even then it will be a much slower process
to relate house numbers to satellite images than to do GPS mapping.
