A very simple but innovative idea for participatory governance - HearFromYourMP is a website that allows constituents to sign up to get emails from their local MP. MPs submit messages, which are then sent out by email to the people who have signed up in their constituency. The messages are also displayed on the website. The constituents who've signed up are then able to post comments on the message via the website. Most of it is open source and the non-profit society that maintains this for UK is willing to help take it to other countries. Any takers? Thanks to Aaditeshwar for pointing this out.
