I think that's probably true. If I wanted to try to monetize it, and invest money in a toy, I'd probably buy a list of websites, from http://www.alexa.com/site

I think that's probably true. If I wanted to try to monetize it, and invest money in a toy, I'd probably buy a list of websites, from http://www.alexa.com/site/sales http://www.alexa.com/site/sales or such, then ask Turk users to give comments on each of those.. That said, I think that where it would be more useful is on a more user-driven system.. If images start making the rounds in email, someone might upload it, find that there was no comment, and enter one, such that the next person would find it.
