In his column on ethics for the New York Times, Randy Cohen answers this question:
"After I was scheduled for a job interview at a university, a member of the search committee Googled me and found my blog, where I refer to him (but not by name) as a belligerent jerk. He canceled the interview. It was impolitic to write what I did, but my believing him to be a jerk does not mean I would not be great at that job, and the rest of the committee might agree. Was it ethical of him to cancel the interview?
