From what I understand TIGER data is very poor quality to begin with

statististics their sample size would be too small to draw a
conclusion
I agree with that. What I've seen from the TIGER data it is not
conducive for a good mapper ecosystem. Yes, it will function to show a
map that is moderately accurate, it might function if you want to use
the data for routing purposes and maybe even for guided navigation, but
virtually all information needs fixing so the amount of work you have to
do to get a correct map is still humongous. And then you get parts which
are corrected and part which are not and the casual dataconsumer can not
really distinguish them.
Compare that with the AND import of the Netherlands where the data was
accurate and needed only minor fixing but where the bulk has just been
untouched (except for adding metadata) and is still the base of the map
in the Netherlands.
So the one import cannot be compared to the other and conclusions drawn
from one can not be extrapolated as being the truth.

Yep.

All to easy to be critical .. but so what?
Getting people to contribute to the map is what it is about.
There is one guy on Quilpie Queensland Australia who has made good
contributions to the map - he is local .. so knows what is there.
The edits may not be the 'best' but they do indicate what is there..
I've edited some of them to make them OSM 'better' but tried to keep
the original information.
Yet to contact him to let him know .. but good on him for putting
his foot in the water.
Don't think there is much chance of getting a local group out there
.. unless you count 1 as a group.
And maybe one is all it takes in smaller places.
Officially Quilpie's population is less than 600.
