Today, the Guardian announces that it is switching to Twitter:

„Consolidating its position at the cutting edge of new media technology, the Guardian today announces that it will become the first newspaper in the world to be published exclusively via Twitter, the sensationally popular social networking service that has transformed online communication.“

Well, funny story. But it also shows that Twitter has become mainstream. And it’s time for all sorts of companies to find out what to do with Twitter, and – more important – with social media in general.
