Let’s add the latest contender:

Scott Brison: If not for Ignatieff, Brison’s would be the clear leader among the various web sites. It has polished design and visual appeal, as well as simple navigation through a wide range of content. There’s an email newsletter, send-to-a-friend features for each page, a volunteer form, full contact information and, yes, not one but three separate news feeds (but curiously, no omnibus feed).

Where Brison’s site falls short, though, is in offering any real sense of interactivity and openness. While Ignatieff’s site has an apparently no-holds-barred discussion forum and the promise of a policy forum, Brison’s site’s public face involves only one-way communication. There’s no blog and no comments (jury-rigged or otherwise).
