... isn't it kind of strange to watch a video of a moment of silence?

Not as strange as joining the live chat.

how about a moment of full-throated rage instead.

@3: I think, perhaps, that entirely too many such moments may be the problem here. Not the solution.

@4: so, a moment of silence is a solution? to what?

@5 Not a solution. A sign of respect for the dead that we all shut up for a minute and take the time to think about what happened.
