Hack for Change will bring together 50 engineers and designers for 24 hours to build applications to generate positive change. Change.org is sponsoring the June 18-19 hackathon in partnership with Mashable and Code for America. “The smartest people in the world are focused on problems that don’t really matter,” said Change.org founder Ben Rattray. “What we want to do is dedicate the time, effort and energy of those people to important issues.” To provide inspiration, the program sponsors are soliciting ideas for apps (the top vote-getter is currently “A widget to draw attention to common good jobs on LinkedIn”) and will offer suggestions at the start of the weekend.
