David Cameron now has profiles on LinkedIn, Foursquare Page and Google+. It’s great to see the UK Prime Minister broaden his use of social networking tools following the setup of a Facebook Page and a Twitter profile earlier this year. According to a Number 10 press release on LinkedIn, Cameron will network with “people and businesses the PM meets regarding U.K. business, enterprise and manufacturing,” and on Foursquare, the PM will check-in to various venues in order to “illustrate the events the Prime Minister participates in during his day-to-day duties beyond Downing Street.”
