The New Jersey Appellate Division has just held ... that a federal statute - 47 U.S.C. sec. 230 - makes Web site operators immune from defamation liability based on items posted by users, even when the operator keeps some messages and deletes others, changes some messages, sets ground rules for the discussion, and so on. This would also mean that bloggers are immune from liability based on comments posted by others on their blogs.
This doesn't mean anything for me directly, but it should spare other blogs of any trouble from comments I might post there. I wouldn't want that on my conscience.
