Well, then I discovered something the other day on the lovely blog Mrs Eliot Books. If you type in a word verification through the program reCAPTCHA you're actually performing a community service. You, dear blog reader, are helping to digitize old books every time you leave a comment on a blog! Don't believe me? Watch this!
It might not stop you from blowing steam out of your ears every time you get the word verification wrong, but it might make you feel okay about using it. And maybe a little self-satisfied ;)
