I think plenty could have happened. Compare with the false nuclear attack alarm in Hawaii the other year. Panic can cause all kinds of unforseeable consequences.
Right, but I think the point is that panic is the only real danger this hack could've caused. That's important in it's own right, but hacking twitter is not going to cause nuclear war. DoD has a ... tentative relationship with social media. They are not making strategic deployment decisions based off of tweets (thank God).
