Judging Criteria

  • Technical Difficulty
    Is the hack technically interesting or difficult? Is it just some lipstick on an API, or were there real technical challenges to surmount? This is the most important criterion that your hack will be judged upon for the general prizes.
  • Practicality
    Is the hack practical? Is it something people would actually use? Does it fulfill a real need people have?
  • Creativity
    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?
  • Polish
    Is the hack polished? Is it free of bugs, easy-to-use, and if possible, aesthetically pleasing?
