Rupert Murdoch joins Twitter: And, on top of giving props to Rick Santorum, he showed a little trouble getting used to stuff. Note the grayed-out entry from this screenshot we took about six hours ago. (It’s gone now.) On top of the lack of immediate profile pic, it seems like someone meant to search when they tweeted instead. Don’t worry Rupe; we’ve all been there. EDIT: Oh yeah, about that Alexander Hamilton tweet — he’s right, Hamilton did start up the New York Post.
