Default Recaptcha

Interesting 10 minute talk by the guy who invented captcha and later recaptca, the later of which is used on bh.tv.

Captchas are the wiggly words you have to identify and fill in on many webforms in order to prove you are human. This guy had the bright idea to use the captcha forms to also help us identify various words in non-digitised documents.
