Guys, let's talk about ReCaptchas, where you click certain pictures to clear the captcha. Sometimes you don't have to click any picture, and I'm fine with that. But here comes the irritating part of these captchas, I finally see verify button after clicking like 50 cars and I say "Thank God", But NOO!! I get welcomed with a message "Please try again", and then click 50 street signs again. 
I hate the whole concept of recaptchas. With the current technology is there any way to detect whether the user is actually human and not a droid / robot. It is waste of time, especially on a cellphone / mobile and when you're in a hurry.
