Can a Blogroll Be Defamatory?

An anonymous reader clues us that the wildly litigious Canadian Wayne Crookes, who has been suing the Internet for defamation, has added Michael Geist to his hit list. Geist is a well-known Canadian law professor and blogger. His offense: linking on his blog to site that links to another site that contains material allegedly of a defamatory nature. (Others would characterize that material as historical facts about Crooks's tenure at the helm of the Canadian Green Party.)
