Markus, take a look at the TIGER Battlegrid! It highlights areas where there have not been a lot of edits made to the original street data import.
https://wiki.openstreetmap.org/wiki/TIGER_Battlegrid Another fun tool for finding things to fix is Improve OSM. http://improveosm.org/#background=Bing&map=2.00/0.0/0.0 Both of tools highlight areas of the highest priority, so you're focusing your energy where it matters most.
