After talking with several folks who attended TransparencyCamp, here are some of the most popular sessions to check out:
Open Data APIs for Elected Officials and Districts
Designing for Government
A Few of My Favorite APIs
Following the conference, Dan Melton, Javier Muniz, Granicus CTO, and Ryan Wold, Granicsu Product Developer, participated in the Voting Information Project Hackathon backed by Google, Microsoft, ATT, Foursquare and Sunlight. With a few other attendees, they built Get Out the Vote Posters (http://www.gotvposters.com), a tool for local organizers in supported states to print out multi-lingual posters displaying the upcoming election and a google map image of the location for the closest voting station. The code is open source, check it out at https://github.com/Granicus/vip_multilingual_posters.
