When you're a billionaire media mogul, you have the luxury of saying just about whatever you want on social networking and mircroblogging sites. Rupert Murdoch's recently registered Twitter account underscores this, and the fact that he's making more waves in two weeks than Charlie Sheen did during his prolonged meltdown proves he's either using Twitter entirely the wrong way or exactly the way it should be. Quite frankly, we're having trouble deciding.

A federal judge this week sided with a man accused of stalking a Buddhist religious leader on Twitter, ruling that the Constitution protects "uncomfortable" speech, even when it may cause "substantial emotional distress." Judge Roger W. Titus dismissed the government's case against William Lawrence Cassidy in a 27-page order outlining the details.

Journalists are now allowed to fire off live text-based communications, such as mobile email, social media (including Twitter), and Internet enabled laptops in and from courts throughout England and Wales without asking for permission, a U.K. judge ruled. Prior to the ruling, reporters would have to issue a request, but that rule has now been removed.

Twitter on Thursday introduced a new version of the microblogging service, one that's built around a simplified design intended to make it easier to follow content you care about, connect with others, and discover something new. Those are Twitter's official intentions, anyway. Unofficially, Twitter is reinventing itself as somewhat of a more traditional social network (think Facebook, Google Plus, and MySpace), even if it won't admit it.
