Carnegie Mellon University's premier beginner hackathon
Is the hack more than just another generic social/mobile/local app? Does it do something entirely novel, or at least take a fresh approach to an old problem?
Is the hack technically interesting or difficult? Is it just some lipstick on an API, or were there real technical challenges to surmount?
If your demo video clear, understandable, and under 120 seconds? Can we understand what you did, and why? Does the demo work? Does your project show care and polish?
Is the hack practical? Is it something people would actually use? Does it fulfill a real need people have?
