BBC News reported a couple of months ago about a British court allowing service of a court order using Twitter. Twitter is, for those who do not yet know, an on-line network allowing users to post short messages that are then broadcast to a list of subscribers. In the particular case, a political blogger named Donal Blarney sought an order enjoining another user of the Twitter service. Because the target of the court injunction had not yet actually been identified, the court allowed the injunction to be served via a posting on Twitter.
