Fight Spam with Re-Captcha. And Digitize Books.
Re-Captcha has to be one of the most ingenius ideas to ever grace the internets. What I primarily use it for is hiding my email from spam-robots. Rather than putting my email address on my blog in plain view for spam-bots to see, I use Re-Captcha to hide it, like so:

How neato is that?
Re-Captcha also offers their service to stop comment spam. They offer plugins for WordPress, Joomla, Drupal, Movable Type — basically all the major content management systems.
“I've seen Anti-Spam tools before. Why use this one?”
I'll tell ya why. Each time a person types a captcha, it helps to digitize a book:
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.
Isn't that ingenius?
