Just over the last few weeks it seems that captchas have grown in length enormously: they used to be about 4-5 characters long; now, on my Myspace account, I usually have to fill out 8-9 characters. Hah! Nobody can escape the righteous wrath of spam. That's why we need true artificial intelligence to deal with it. (I won't make any bad jokes about the relative lack of natural intelligence on this planet, of course, nor about my addiction to self-referential statements. Consider yourself warned).
