[OSM-talk] The world’s best addressable map

Steve Coast suggested changing the mission statement of OSM to be something
like “The world’s best addressable map” I thought I'd separate out this
into a new thread. As some backup, I attended my first SOTM-US in 2012
where Steve proposed we build an addressable map. A group of us from
Seattle decided that we'd take that challenge and import addresses for
Seattle. That import was completed.

Here are the address related comments:
