The BBC news website has a popular story on OSM over here. Money quote:
Atlanta, the capital of the US state of Georgia will soon be the world’s most digitally mapped city, according to organisers of a massive “mapathon”.
OpenStreetMap, or OSM, is behind the effort to produce a map more accurate than anything else on the market.
The story has been in the top shared box (look on the right) for most of the day. Awesome!
