Captcha

The other day I discovered reCAPTCHA , one of those really innovative nifty little ideas that warm my heart. Everyday all of us netizens use so much of our energy fighting the evils of spam - service providers keep warding off waves of attacks, while the users keep assuring providers through various means that they are not bots working on behalf on the dark side(read spammers). One of the ways of ensuring that the person accessing a web page is actually a human is to pass the CAPTCHA test.
