I highly recommend watching the TED talk by Luis von Ahn, creater of CAPTCHA and reCAPTCHA. He calls this "human computation". He is also the founder of Duoling

He's also one of the few famous entrepreneurs from Guatemala.

  That's fantastic. I was trying to guess from the name. Latin American? German? Vietnamese?

    Most likely of German descent. I seem to remember when travelling through Guatemala about 10 years ago that one of the locals that I got to know explained that the wealth in Guatemala, especially around Antigua, is concentrated in a number of immigrant families of European (primarily German) descent. There are about 13 large families and they tend to marry within that group.
