I’ve set up an experimental street name comparison service at http://qa.poole.ch/ch-roads/ , this generates on a per community base a list of names and compares them to the list available generated from GWR data. More information can be found here http://wiki.openstreetmap.org/wiki/OSM_-_GWR_Street_and_Place_Names_Comparision
As can be seen from the list we have a large number of locations where we have surveyed none or only a very small number of the street names. I hope that providing this service will help motivate the community to improve the situation.
