Twitter has created a parallel universe of conversation in most social settings these days, including Parliament. Some members tweet from inside the chamber, passing remarks they would not be permitted to say out loud. Does it matter?
The Speaker - David Carter - has referred the use of Twitter by MPs to the Privileges Committee following some controversial tweets, including Trevor Mallard's tweeted comment that Mr Carter "looked like a Mafia don running his @NZNationalParty protection racket".
Mr Carter should lighten up. There is a difference between a comment made aloud to the House and one that is transmitted silently by text.
One is heard by everyone present, the other can be ignored. Mr Carter might not have been aware of the message on the phones of Mallard followers if National's Leader of the House, Gerry Brownlee, had not told him of it.
Rules governing one medium of communication need not always be applied to another.
