I'd like to be able to pay other people to phone up companies on my behalf to do things like closing accounts or changing my address on accounts. Ie, so I could go to a website and fill in a quick form with the following info:

Phone water company X on phone number N Close my account Information you might need: My name is Y, my account number is Z, my address is A and my password is B

I hate having to speak to people whos job it is to try and stop me achieving my goal, ie cancelling accounts. And having to wait on hold, and having to phone back when the call queue is shorter. etc

I guess you could create a dedicated API wrapped around Mechanical Turk, and then stick a website in front of it.
