I think I see the flaw in your logic.

What could possibly go wrong?

In a ruling yesterday, the court created a new defence against defamation suits that it termed “responsible communication.” This defence can protect defendants in defamation suits who have made factual errors in their reports or commentary as long as they can prove they took reasonable precautions to ensure their story was factually correct and that they can show publication of the story serves the public interest.

I can see the defense now: "Hey! Every other Blogging Tory was saying it, too!" There really are some situations for which the phrase "self-correcting" will probably never apply.
