Probably the most massive example of collaboration... to a useful end

Well, how smart can one get in using the wisdom (and time) of the crowd? This guy is probably reaching the highest level anyone can get in efficient crowdsourcing... in fact, in my eyes, his projects are combining a multitude of megatrends I cover:

• crowdsourcing -but than at a scale rarely experienced...
• disintermediation... -if I was a translation bureau I'd get very worried...
• microtasking
• social entrepreneurship -well, the 'microtasking' part could turn into this...
• gamification -in a way people would be contributing to business goals by having fun (or by learning in the meantime)
