So I just had to watch the video he was referring too, and the above screen-shot is how it ends. I know I spoiled the punch-line, but it's still worth watching so click the link and enjoy!
The presenter, Nathan Eagle, has started a service in Kenya and East Africa, called TextEagle, which allows mobile phone users to complete small tasks by SMS and get rewarded for it, in airtime or in credit. For a workforce living on $5/day and eager for more airtime, this works like a charm. Tasks include simple text translation services, local news reporting, and even listening to advertising!
This really is 'crowdsourcing' in action.
