Google Reader Productivity

One of the overlooked productivity features in Google Reader are those little trash can icons in your personal Reading trends (home -> trends -> Reading trends). Just hit unsubscribe for the feeds which consumed most of your time and make room for an extra hour each day.

OCRsourcing

Not as cute as Asirra but an excellent example of how to get microtasks distributed done: reCAPTCHA (stop spam. read books)

About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that’s not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into “reading” books.

Brilliant idea: reCAPTCHA mashes up the shortcomings of OCR software when digitizing books and the shortcomings of the web when fighting bots and spam. It extracts value from CAPTCHA systems by sending 2 distorted words: one of them not read correctly by the OCR tool, the other one already known. If the user has the known one right it is assumed the other one is right too.
