Sweet, docile old man Rupert Murdoch is having a lovely time on Twitter, keeping his merry band of followers entertained with tales of his daily exploits, including why buying MySpace was one of his Worst Ever Decisions, the silly fool.

In a message on the site he admitted that there was nothing in the purchase that had gone right but at least he'd learnt a few life lessons along the way.

"Many questions and jokes about My Space. Simple answer - we screwed up in every way possible, learned lots of valuable expensive lessons," he wrote, with refreshingly candid honesty.

Expensive isn't even close: he bought MySpace for $580m in 2005 just a year before Facebook launched and within five years was selling the company for a paltry $35m, a staggering loss of $545m.

What Sneak is more interested in, though, is a Tweet that appears to show Murdoch sent a personal message to Twitter by mistake. How else do you explain the cryptic message, "Jack. Tokyo sounds great but be careful of that full moon".

The full moon? Why, is this Jack character a werewolf of some kind? Or is the media mogul perhaps a closet fan of Japanese author Haruki Murakami?

We can only hope this is indeed what happened and that in future a more racy, or indeed, incriminating text is sent to the wrong location.
