Pun unintentional! 
Thanks, Alex; we are quite open (and sometimes quite vocal) about the fast that OSM is our source data for streets, and we’ll continue to advocate.
One option we’ve considered is making it as easy as possible to add this information using our site. That is; if a road is un-named (or mis-named), or house numbers are missing, we make it very simple (just a couple of clicks) to edit the OSM data. Think of it like a very cut-down Potlatch, hosted on our servers, just for adding geocoding information.
Cheers
Ben
