Hurricane Hackers is a hashtag on Twitter (i.e., #hurricanehackers) and a crowdsource hub to create tech and social projects related to Hurricane Sandy. Proposed projects include an ad-hoc food and water delivery system for after the storm and live maps that show which businesses in a given area are actually open. You can propose projects or start working on projects other people have proposed. Check out the official Google Doc, or the IRC channel. (Via Shasha Costanza-Chock)
