Sorry Mike, i dont agree.
Assume for a moment that you discover online an article written by a journalist stating that the CEO of your company is involved in embezzlement & money laundering.
By your reading of the law, your passing of a link to that article to the board of directors would be defamation and you would be liable. However, i would argue that if you discovered such an article it is your moral duty to pass that article across to the board as if its true, you, your co-workers and the investors are likely to wind up out of jobs and out of pocket!
By your reading of the law, a person must conduct there own investigation of the facts in the article first to determine whether its accurate or not, before you can ever link to the article. This seems patently ridiculous to me. If a journalist or blogger makes defamatory statements online they had better have the evidence to back up what they say. If not, for sure they should be sued for defamation. But to sue someone for posting a link is ridiculous.
