It happened to Anthony Weiner; now it happened to Twitter CFO Anthony Noto. No, not sexting, but both posted tweets they thought were sent as direct messages. 

Speculation about which company Twitter is planning to acquire abounds, but spokesperson Jim Prosser confirmed only that Noto intended to send the message privately. As a Twitter executive since only July, maybe Noto is still learning the system. He deleted the tweet.

Discussion Starters:

• Explain to a novice the difference between a tweet and a DM. 
• What else, if anything, should Twitter say about the situation? In addition to deleting the errant tweet, should Noto comment on the mistake?
