Can the 'Wikipedia of Maps' Challenge Google?
OpenStreetMap is an open source wiki of maps and location data, much like Wikipedia is a wiki of information you find in an encyclopedia.
"In what seems to have been a surprise to everyone, the prices that Google asked of its heaviest Maps users apparently dwarf the revenue of at least some of those sites, which is leading to a very public move away from Google and to OpenStreetMap," writes author Christian Mims.
"Some areas, particularly in Europe, where contributing to OpenStreetMaps is something of a craze, its maps are updated more frequently than Google's maps, and contain vastly more detail."
