Twitter has private messages and public tweets. It may soon have something in-between: a "whisper mode" that lets users choose who can see a conversation. Here's TNW's Emil Protalinksi, quoting a Bloomberg interview with CEO Dick Costolo.
"There are frequently public conversations that you would like to grab hold of and take into whisper mode with a friend and say, hey, this thing has happened. Look what these people are talking about. What do you think about this, with a friend or more than one friend. So being able to move fluidly between that public conversation and the private conversation is something we'll make simpler."
This will end in tears.
