CAPTCHAs

you're working even when you don't realize it.
apparently, every second counts.

you know those strange melting letters and numbers you have to interpret and type in when you're registering for something or other online? researchers at CMU have found a way to have those CAPTCHA moments contribute to digitizing books. unrecognized sections of scanned text are used instead, and when people interpret the jumble, it gets sent to a database. don't worry--it compares multiple people's intrepretations before making any final "decisions."
