One New Thing: reCAPTCHA.

Well, it's been a long time between posts. But I've just found something very cool I'd like to link to: reCAPTCHA. CATCHPAs are those images with words in them that you have to type into some webpages - reCAPTCHA is a project that takes words that can't be read by OCR software when pre-digital-age books are being digitised, and displays them as CAPTCHAs in places where real live people can identify and type the word correctly. Spam prevention and book digitisation combined!

Link via EcoGeek, which is a very interesting blog that you should check out if you don't know it already. :)
