That being said, it wouldn’t be too hard to hook up the same interface to a different data source.” Code for America will help Chicago to implement Open311 in 2012. Eder shared that he wrote a script that converts Socrata to Google Fusion Tables that could be modified for this purpose. is one of a growing number of civic applications that have come out of Chicago’s open government initiative. As Eder made sure to point out, his app is a finalist in the Apps for Metro Chicago contest, along with 9 other apps, including iFindItChicago and Techno Finder.

In the video below, Elizabeth Park, the creator of IFindit Chicago, talks about how she was inspired to build the team that created an Android app to help homeless and lower income citizens find resources like as shelters, medical clinics,and food pantries.
