The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct."

Which, of course, serves to highlight the fact that the user is asked to do
twice the work for the
same reward.
Thank you for presenting that fact. I'd deliberately made no mention of such so as to avoid giving the appearance of merely bashing this particular implementation of CAPTCHA for no good reason.
It should also be noted that the "words" - some are not words at all, but seemingly random character strings - here presented are significantly less readable than those of predecessors, with the result that an even greater number of people are turning away from Ticketmaster (TM), and to the very people who TM seeks to displace, the independent ticket brokers.
The bottom line is that people do and will not like CAPTCHA that relies on their ability to recognize a deliberately obfuscated string of discreet symbols.
