• The Obama White House is quick with a warm welcome to the Twitterverse.

• "Are you sure you want to do this?" The email record of World Cup bets between English and American diplomats.
• Utah Attorney General Mark Shurtleff announces an impending execution via tweet, and then follow it up with the note, "We will be streaming live my press conference as soon as I'm told [the prisoner] is dead."

• Mashable has a look at Elena Kagan's mailbox.
