PeopleHunt demoed its new iPhone app at last night’s NY Tech Meetup. The Next Web reports that the SoHo-based company’s app turns the idea of Meetups into spontaneous get-togethers based on “things you can show, tell or teach one another.” The app taps users’ Facebook groups and other groups like NY Tech Meetup to form a new network of people. After a group is formed, users can submit things to share or search for information. Network members can introduce themselves and chat. The app has just left private beta and is globally available.
