Edward Snowden joined Twitter yesterday after working with the social network to get the handle @Snowden for three years. His profile says “I used to work for the government, now I work for the public,” and his first tweet showed his cheeky side: “Can you hear me now?” In less than 24 hours, he’s got over 1-million followers while he’s only following one account – @NSAGov. Since the story of the NSA’s mass surveillance of Verizon phone records went public in June 2013, Snowden has been mostly out of the public eye – but now that he’s joined Twitter, this will probably change. Should Twitter ban Snowden from having an account? Could he possibly put people’s lives at risk with a single tweet?
