Bloomberg: After six years in the White House, President Obama has his own Twitter account. “Hello, Twitter! It’s Barack. Really! Six years in, they’re finally giving me my own account,” the president said using the verified handle @POTUS, anticipating skepticism about his new social-media presence. The move is “a new way for President Obama to engage directly with the American people, with tweets coming exclusively from him,” the White House said in a blog post.
