The Long Now Blog » reCaptcha your wasted time
One of the inventors of Captcha’s, those funny squiggly words used to prove your a human when you sign up for something, has now put this wasted time and human brain power to work.

ReCaptcha is now getting its difficult to decipher words from scanning projects like the Internet Archive’s and is using the human effort to digitize the words the computer cant recognize. Over a half million man hours a year can now go to digitizing books instead of just wasting your time.

Turning waste into fertiliser. Excellent.
