Citadel: Turning Citizens into App Developers using Open Data provided by Cities
What is the best way to discover a new city? Following the recommendations of a guide? Reading a Wikitravel article? Watching a documentary? While I find these sources useful, I prefer to consult the people who know the city best: its citizens. If you had the chance to talk to a local who is passionate about his or her home town, you will probably agree that citizens are the most valuable asset a city can have.
