Tempe is collecting public feedback through a Google doc on its open data policy and open data portal, which launched May 22. To solicit input from the public on their respective open data policies, which are not yet finalized, both Glendale and Nashville are using a platform called Madison, designed by the OpenGov Foundation specifically to host public comments on drafts of policies and legislation. In Durham, officials are working to improve and build upon an open data policy that is already in place, also by using Madison. In addition to Madison and Google docs, cities have also used GitHub to collect such feedback.
