I’m sitting at DLD, a new-media conference hosted by an old media company (German magazine publisher Burda) in Munich. Arthur Sulzberger Jr. of the New York Times Co. and Hubert Burda of Burda are onstage talking about their experiences in a transformed media landscape. I want to feel useful, so I start tweeting about it. I am not alone. A trickle of tweets with the #DLD11 hashtag soon becomes a roaring river, to the point that blogger Paul Kedrosky, who’s not here, complains about it. One of Sulzberger’s utterances — “a New York Times article is tweeted every four seconds” — is itself tweeted every 10 seconds for an hour or two.
