I have been playing the Photohunt and am currently in the lead - it is very fun! Thanks for building the Human API - I have many great ideas using this and have been taking notes to help improve the process. Contact me Hacker @ myusername ORG
Everything is generated by the client. The tasks, the photos, the voting, are all happening in the human.io client. The rest is just driven around by the script. They write to a database, and the web page is just pulling from that database.
This would be easier for you to see if you installed the human.io client.
I've long thought that something like this, combined with something like twilio, would be killer for letting companies build ad-hoc customer support teams, and letting end users work their way up a customer support ladder (think small ecom sites that don't need a fulltime helpdesk but do need to handle inbound calls occasionally). You could build out a CSR script and route calls accordingly when people call your support line, and use human.io to put the data into your ticketing system / whatever.
(I know that's not what it does. But just illustrating my point. Don't make me, the user, figure it out. Just tell me.)
