Lady Gaga may rule on Twitter, but President Barack Obama earlier this week officially became Foursquare's most renowned user yet. Now, the rest of us will get to see where the most powerful man in the world visits with foreign leaders, speaks at town hall events, and, who knows, maybe he'll tell us where he goes on vacation. The White House has stated that it will utilize President Obama's Foursquare page to promote a current economic bus tour as well as future events. And with the 2012 Presidential election just over a year away, the White House will undoubtedly push campaign-related stops and get the President's message out. It's never too early to start campaigning, right?
