This is really cool, and I'll definitely be checking it out, but "If Twitter is HTML, then Human.io is CGI." has to be the worst pitch line ever.

Human.io provides a robust platform for creating mobile activities for people to perform in real life. Quickly create interactive apps that take full advantage of mobile GPS, video, and photo capabilities, promoting rich responses to surveys, games, or contests. Plus, using our integral filtering API, you decide exactly who gets to see and run your app. Push out your app to people based on location, demographics, or your own custom filters.
