Since the earthquake on Haiti in 2010, the media have produced a significant number of articles on crowdsourcing information curation in the context of crisis management. They have tried to follow the developments closely, since in their research they are trying to harness the power of the crowd for improving situation awareness of public and decision makers during a crisis event.
The most important arguments made by the author seem to be:
1. You cannot be sure that the crowd is there when you need it. Depending on other events happening, or the geographic area affected, there might not be a sufficient number of volunteers.
2. The basic needs of most members of the affected communities are always the same: Food, water, shelter, basic medical aid.
3. Uncertain reliability needs re-checking of information, and the information is of very transitory nature.
