Celebrities constantly generate attention on the microblogging Web site Twitter, but Rupert Murdoch is a media mogul, and because he is so new to Twitter, his messages provide some insight into the powerful man's mind. That was particularly evident when Murdoch took some time out during International CES to muse about how terrible an idea it was for his company News Corp to buy MySpace back in 2005. News Corp shelled out half a billion dollars for the social networking site and recently sold it for a tiny fraction of that.

Many questions and jokes about My Space.simple answer - we screwed up in every way possible, learned lots of valuable expensive lessons,Murdoch said in his tweet Jan. 12 from Las Vegas.

It may be easy now to look back and say it, but at the time of the purchase, Facebook was only a year old, and obviosly no one at News Corp. thought Facebook would blow up like it did. In the tech world, deals don't always work out (see HP's purchase of Palm), but News Corp. is one of the biggest tech/entertainment firms in the world, so the deal didn't cripple them. Now that the company has washed its hands of MySpace, perhaps Murdoch will tweet about some of his other companies' failures. Any insight he could give on the mess that is the News of the World phone-hacking scandal News Corp. faces would be most welcome, if unlikely.

Murdoch joined Twitter early in January 2012, so he doesn't have enough tweets to create a bona-fide Internet meme yet, but there is a fake Wendy Deng account that is kind of buzz-worthy. Deng is Murdoch's wife, and when the fake account went life, Twitter accidentally certified it as the real thing briefly. The owner of the account came clean only a few hours after the certification, but between the two Twitter accounts, it should be a fun year to follow their progress. Tell us in the comments if you have a Twitter account and who's the best to follow.
