So if he did tweet, how might David Cameron have summed up his press conference this morning? ‘nice easy questioning, avoided getting pinned down on tax rises/public spending, backtracked quite well on Edlington.’ That was my immediate offering. A quick ‘Cameron’ search on twitter suggests many alternatives.

He explained that one of the reasons he is resistant to joining the ranks of the twitterati is his evident concern that he would not be able to think through what he would say. That sounded very odd. As he said, as a top flight politician, he is constantly communicating in different ways, and thinking on his feet, so I found his lack of confidence about his own ability not to screw up in140 characters a tad alarming.

But then I wondered if perhaps this is his way of signalling that despite what most who were tweeting during the event seemed to think, he is actually a man of great substance, so great that it is impossible to reduce his great substantial thoughts and policies to 140 characters. ‘Cameron – too serious to tweet’. Try that one on the next airbrushed poster.

It may be that he thinks he cannot get his thoughts into short bitesizes, but in truth, as the press conference showed once more, he speaks a lot, yet says so little.

When the transcript comes to be typed up, there will be a lot of words down there, a lot of questions on a lot of subjects, but actually very little that couldn’t all be summed up in a tweet or two.

Fixed term parliaments? Good idea, er, but bad idea. Prison ships? Need more prison places. Not sure how to get them though. Marriage in the tax system? Sounds great, still no clearer how we do it. Deficit reduction = tax rises/spending cuts? Avoided Nick Robinson. Adam Boulton had a go. Avoided him, but they noticed. Managed to avoid without sounding like I was avoiding. Phew.

Best mid-event tweet in my eyes the one that asked ‘has Cameron just admitted to having long-standing credit card debts – these millionaires’.
