Captcha

Captchas have been in the news recently. Apparently computers can do a reasonable job at guessing them. I can't, thats for sure, but I can guess how I could write a program that could guess better then me.

Although, nobody is sure if it is computers or a room full of slave labour doing the guessing. But somehow they get a success rate greater then 26^6.

I am guessing the one here is xtuixj, but one can never be sure. It took me three failures before I got though blogger's captcha today.
