I've been hoping for a Captcha alternative for a long time. I wouldn't inflict this upon my users. There must be several Captcha generators. I find myself doing at least one "reload" on all of them these days. I find Google's Captchas utterly illegible: password re-entry is difficult, at best. A "kinder and gentler" alternative is in order, such as the question-answer I've seen. E.g. "What is 18 plus thirty three?"
