It is interesting that David Cameron hams it up to try to please particular audiences. It so transparently contrived. Just after elected Tory leader, he appeared on a London community radio station for the "young". When asked to give a message to the audience he said "Keep it real".
Come off it. This man was brought up amidst antique family furntiure in one of the poshest parts of Berkhire -Leckhamsptead. I've been there several times. "Keep it real" is not a phrase you hear in the Stag pub there. "Yah", "Ew" and "Tally Ho" you might hear. "Keep it real" - no.
So today he tries it again. He's on with zoo radio expert Christian O'Connell, so he swears. "Tw*t" and "P****ed off", he says. Oh yes. He's really down with the kids. And Ew, marvellous, some excellent press emphasising his street cred.
Except there is a fly in the ointment:
Asked whether he used Twitter, Cameron said: "The trouble with Twitter, the instantness of it - too many twits might make a twat.
Do you see what he did there? He's a tw*t because he hasn't used Twitter and obviously has no idea what it is, and, let's face it, expecting him to use it would be like expecting Her Majesty the Queen to use the iPod that Bazza gave her and load it herself (I love to think that she has "God Save Oneself" loaded onto it, but I fear not).
But he's turned it round and called all us Tweeters tw*ts, effectively.
That will come back to haunt him.
