I agree with this.
First problem is building the map, the the second problem is improving the quality.
Currently there is more incentive to spend time challenging other peoples POIs than there is to place a new POI even though there are a billion… literally, a billion, POIs that should be added.
The incentive to challenge POIs and the incentive to add new POIs should be inverse and should be based on the amount of activity in an area. Consider in a place with a POI registered for every 1000 sq ft, the incentives should line up to encourage the challenge of existing POIs. Conversely, in situations where the number of POIs marked are sparse, (like in the maps current state everywhere in the world,) there should be almost no incentive to challenge others POIs. If people are going to spend time on the map, they should be marking new POIs so that we at least have a base line to start from. incentive to refine that map should increase as the map gets more points on it.
