I think letter writing campaign and petitions accessible from the computer are a good way to keep individuals interested in politics. Online media also helps giving people an ability to feel like they matter no matter how small the situation. Accepting micro donations from the computer also helps people keep their interest since they can speak with their money, and feel like they are part of something greater than their individual lives. Blogs teach us that are thoughts matter even if they are just for private or inner circle activity.
The democratic deficit must be fought or economists will rule over political scientists and treat the population like an ant-hill.
Edit: Yeah, it’s nice and all, but is it enough?
