Over the last several days there has been considerable hubbub around the notion that pioneering media theorist Jürgen Habermas might have signed up for Twitter as @JHabermas. This would be “important if true”, as Jay Rosen put it. Intrigued, I tracked him down through the University of Frankfurt. I succeeded in getting him on the phone at his home in Sternburg, and asked him if he was on Twitter.
