The deleted tweet

A few minutes later, reports the Sydney Morning Herald Mr. Murdoch's wife came to his aid. "RUPERT!! delete tweet!!" Wendi Deng wrote, "EVERY1 @rupertmurdoch was only having a joke pROMSIE!!!"

She quickly followed up with: "explaining to @rupertmurdoch about being careful with humor on line. sometimes it comes out as rude!"

While some doubted that this was an official account, it has been verified by Twitter and its CEO Jack Dorsey, who chatted with Mr. Murdoch via tweets.

"With his own voice in his own way, @RupertMurdoch is now on Twitter," Mr. Dorsey wrote. In his next tweet, he said his resolution for the past few years has been to simplify.

Mr. Murdoch couldn't resist the opportunity for a little put-down. "Right on simplify but easier in startups. My resolutions, try to maintain humility and always curiosity. And of course diet!"

Mr. Dorsey wasn't going to take any guff on his own service, "@RupertMurdoch you can definitely simplify big companies too. They need it the most. Try it this year."

Killing two birds with one stone, Mr. Murdoch pwned Mr. Dorsey and gave himself a pass on recent scandals, "@jack you are right and we try all the time. But wait till you have 53000 people across sixty countries with different laws,etc," Mr. Murdoch fired back.

It certainly seems like Mr. Murdoch will be an exciting addition to Twitter; that is, until his lawyers get wind of this.
