Just a quick note, re my previous one about the 'project' to fix the duplicate search results for US counties by linking the boundary relations.
I'm keeping a 'informal' worklist here... http://wiki.openstreetmap.org/wiki/User:Revent/Counties because I'm OCD and want to know they are all done.
Currently we have over 1100 counties done (out of about 3400), so approximately 1/3. More volunteers to do your local state welcome! :P Letting me know that an area has been done would also be nice, so I can mark it off the list.
ToeBee has a nice blog post about an efficient 'workflow' for fixing a state with JOSM here... http://ksmapper.blogspot.com/
