UK Prime Minister David Cameron has joined the 500 million people that make up Twitter's user base. Technically, Cameron already had something of a presence on Twitter. Number 10 Downing Street has been part of the service for quite a while, racking up 4,000 tweets. However, that account is more for the Office of the Prime Minister and would likely stay that way even if someone else were to assume office. This new account, under the handle @David_Cameron, is specifically for David Cameron.
So far, the Prime Minister has tweeted only 10 times, having joined the micro-blogging site three days ago. He is following just 34 people, the majority of them politicians, but has already amassed well over 100,000 followers. Aside from tweeting about political issues and appearances, the Prime Minister doesn't seem opposed to sharing some more personal moments from his life. Yesterday he revealed that his staff had taken time to celebrate his birthday despite his busy scheduled and included a photograph of him with two Colin the Caterpillar cakes from Marks and Spencer.
Around this time last year, Cameron joined LinkedIn and Foursquare. He also has an active Facebook page.
