Release the hounds — I mean, tweets… The 80-year-old CEO of News Corporation, Rupert Murdoch, has joined the microblogging platform Twitter. And it is the real deal — the Twitter handle @RupertMurdoch was verified as authentic by Twitter founder Jack Dorsey — who tweeted out “With his own voice, in his own way, @RupertMurdoch is now on Twitter.” The scandal-ridden media mogul has attracted more than 22,000 followers in less that 24 hours — and he’s sharing his favorite things, usually related to Fox, Wall Street Journal and the NY Post. His first tweet was a favorable but brief review of Matt Ridley’s book The Rational Optimist — “Have just. Read The Rational Optimist. Great book.” Murdoch was also reflective on the late Apple CEO, tweeting “Steve Jobs biog interesting but unfair. Family must hate.” He’s not using any hashtags, yet, and is only following four others — Google’s Larry Page, Zynga co-founder Mark Pincus, Dorsey and Lord Sugar — a British technology entrepreneur and friend.
