Captchas I Can Actually Support

I really don't like Captchas, the squiggly words that many websites use to protect forms from spam bots. Unfortunately, sometimes they are the only thing that can protect a site from clever spammers.

Yesterday I heard a great story about reCaptcha, captchas that are used to crowd-source digitizing of old print books and newspapers on NPR. If you have ever tried to use a scanner with OCR, you know that it can be pretty hit or miss.
