The Twitterverse is still recovering from the sudden departure of Courtney Love and her daughter.   Courtney Love has closed down her Twitter account just days after her daughter, Frances Bean Cobain, went after Ali Lohan — Lindsay’s sister — on the micro-blogging service. Mother and daughter are both tweet-obsolete for the moment.

Love is dealing with a defamation claim after tweeting disgust at a fashion designer, and Demi Moore and Perez Hilton were also exploring legal action after their war of 140 characters or less with each other last month.

The law on what you can and can’t say on Twitter hasn’t been refined yet by a court, but assuming it follows the general defamation book, it’ll be hard to win a defamation lawsuit. But that won’t stop many plaintiffs from trying.
