Jim Webb's Slanderbox
This may be the single worst interactive feature we've ever seen on a high-profile Politician's website. It's from Jim Webb's "Born Fighting" PAC, and it seems to be designed for filthy jokes, libel, and anonymous insults -- all of which are displayed, continuously updated, on the front page of the website.
Maybe what they don't tell you is that if you write something insulting or use a false name Jim Webb will personally come to your house and punch you in the face.
