CAPTCHA

CAPTCHA is a program where it processes thousands and thousands of old books. It processes them in a way that it gets words from those books that are hard to read, humans type in the word for the computer so that it gives it a word like that or exactly like the word. It is also to stop people from spamming on your blog/site. About 200 million people solve these word problem everyday. Every word takes about 10 seconds to solve unless you refresh the word, each day it takes 150,000 hours in a total of solving. One of the words is and easy word that the computer knows and another word that the computer doesn't know.

I think it would be good for sites like Facebook and other social networking.
