•  Justine Sacco's tweet certainly has some racist overtones, even if (we assume) she was trying to be funny (and failed). But does that make her a racist? Think about her situation, but also think more broadly: does a single tweet (or Facebook or blog post) represent the entire person? If we found another tweet that said she headed to Africa to do humanitarian research, would we be able to reconcile those two images of her? And do either or both of those tweets tell us anything about her onground life?

Consider the Sacco situation and any other situations that you have read or heard about, or experienced yourself, and respond to this question: Is the person we present online the person we really are?
