Ben Lorica at O'Reilly Radar – Mechanical Turk app on the iPhone Provides Work for Refugees:

"The turks in the refugee camps are recent graduates of Samasource's computer training program. Rather than sitting idly while they wait to be employed, they earn money performing simple computer tasks for real companies. On the other hand, Give Work app users volunteer to perform simple tasks on their iPhone knowing that refugees in Africa are benefiting. CrowdFlower founder Lukas Biewald notes that their work with Samasource opens up their platform to companies who want to tap into and help micro-workers in developing countries."
