One thing every blogger can agree on is that spam sucks valuable time away from what actually needs to be done. One solution to this issue has been Captcha, which is one method for figuring out if a creator of an account is really human. But, the captchas actually lock out the visually impaired if not designed correctly. Apetitionhas been started to ask Yahoo! to make their site, and captchas, accessible to the visually impaired.I discuss this issue more at my blog.
