You mean few small (relatively) communities did this for themselves, because it was obvious no one will think about them and in most cases ordinary user doesn't care much about their input. I am talking about an average map user, globally. If you want global coverage and relying on people to input data, then good luck. I do really like the idea and I wish with all my heart that people would be that generous with their time and effort but we have to face the truth - people don't care, people want a working and complete service. Unless there is some automation in place and free data exchange OSM will never be first choice for general public. Idea is beautiful, execution... Well, Tokyo city, population goes in millions, buildings and addresses not available farther than few blocks away from the train stations. You can see roads but roads in Japan have no meaning. And yes, I could input my house (just 10 minutes from station, blank point on map) but sad truth is, I am unable to input all of them and as you can see - people don't care. They just use Google Maps.
