At Podcamp New Hampshire I attended several interesting sessions and one of them was Walter Elly's talk on Foursquare, a location based social media tool. It opened my eyes to the amazing opportunities that phones with GPS provide to both businesses and the average person. I think it's another remarkable enabling, leveling technology. I don't know if there's a video opportunity here, but I'm betting there has to be. Do you know of any ways that video fits in this new media space?
