1/ It's a fraud, despite Twitter's certification that it is genuine.
2/ If it is not a fraud, then it is time to short News Ltd stock. The silly old bugger has lost his marbles (before Wendi's kids can battle Anna's brood for them in Probate Court).
Actually, regardless of the account's authenticity, there is some evidence to suggest #2. If you had clicked the above link just a month or two ago, it would have taken you directly to The Australian and scored that newspaper an extra visitor. Now you will hit the paywall and probably end up clicking through to the Silly, which, dopey as it is, isn't half as silly as Rupert when it comes to getting a handle on this new whizzybang interweb thing.
At the Billabong, the betting is on fraud -- a view bolstered by the just-too-convenient Wendi Deng's neatly dovetailed twitter account.
Anyway, have a peek at @rupertmurdoch and @wendideng and stayed tuned.
UPDATE: Someone else needing to be convinced.
UPDATE II: We'll know it is genuine if something like the following tweet appears:
Not appealing Mordy's verdict on Bolt because must suck up to Gillard. Have sent her Glenn Milne's head but she wants $17,000 voucher at Town Mode to be nice.
