It's still funny a company awash in money wouldn't just hire people to do this.
And I'm quite sure people criticizing this won't be using it :)
Because it's cheaper and it's clearly working. I doubt someone doing this as a full time job would be as good at these monotonous tasks than 10 times as many people who are doing it for a few minutes per day.
It could still be called "crowdsourcing" if it were compensated.
