On September 4, the Green Party of Canada announced they were dropping John Shavluk as a candidate because of allegedly anti-semetic remarks he made in a comment on a blog.
To me, the main lesson there is that the Internet Remembers. At the risk of making light of a serious situation, it is worth noting that if Mr. Shavluk had done a better job of quoting rather than just "parroted what others were saying", this story might have had a different ending.
