In Australia, Twitter Might Face Defamation Charges

Lawyers in Australia seem to believe that a case could be made that Twitter is a publisher, like a newspaper, and therefore it can be sued for defamation as a result of a single tweet. That may be a stretch — especially in the United States, which has legislation that protects online commentary from such lawsuits — but it highlights the difficulties that Twitter could have as it tries to expand around the globe and into different legal environments.
