Hi all, I've been working on my startup, Mobtropolis. It's a service that helps you find, record, and share interesting experiences in the local world around you. An easy way to think of it is as a photo scavenger hunt or photo dare site. It uses social news and game mechanics to help coax you to experience the world and take pictures as proof. Photos can be submitted through your camera phone or through the web from your digital camera. It's at a point where I would like some feedback from YCers, so any feedback or insight (positive or negative) is welcome, so I can keep improving it. And if you know of other specific groups of people that would find it useful or fun, please let me know. Thanks. :)
