Bring Sunlight to Issue Forums
The Sunlight Foundation provides APIs for accessing information on the federal and state governments. Plus, there are convenient python libraries for these APIs.
Some of E-Democracy's largest groups are the political issues forums, such as Minneapolis Issues and St. Paul Issues, which are great testing grounds for how to bring Sunlight's information to the public discussion.
Provide Relevant Info
One fairly easy idea is to search Sunlight's API for the keywords of a topic, and then display the returned information to users who view that topic.
