Michael Rosen and Keith Houston
MR: Quite often I notice on Twitter and places like that people misunderstand irony. I mean because we only have text in front of us not intonation. So do we need an irony punctuation –'hello, I'm being ironic now' – do we need that?
KH: You might say that emoticons are the best way to go about that – a little winking emoticon – you know, semicolon, dash, closing parenthesis.
MR: Oh yes, yes, of course - they've invented all these with the punctuation that we have on the keyboard.
