The Interactive Democracy web site should be designed to enhance debates. Any voter can contribute an opinion or question (without being abusive), structured as threads and categorised as Plus, Minus and Interesting Points. These posts may at times link to external sites (which may be removed by the webmaster if they are found to be abusive).
MPs contributions to the debate should be highlighted and the site should have the facility to filter out all other contributions, leaving the Parliamentary debate clear and easy to follow. This would not only allow us to focus on the core issues without wading through vast numbers of posts, but would allow us to judge the qualities of the MP, and the pressure exerted on them by this public spotlight will encourage them to contribute effectively.
The site should also encourage MPs to present their evidence, which may be in the form of academic or government reports. They will therefore act as editors, ensuring that credible reports are presented on the secure site, both as highlights and the full document. The flip side of this is that academics, who may want to present their work, would be well advised to present it to MPs and persuade them of its merit. Unlike links to external sites, these documents wouldn't be corruptible after the link was posted.
Finally, each contribution, from MPs or voters, may be judged by the public on its relevance to the debate, allowing users to filter the debates to find what others perceive as the most crucial points.
