I saw the argument yesterday that was made and it was good enough to convince me that Twitter and Facebook should stay up. They are important communication tools and they will be needed today when people are going to those sites so they can discuss this stuff. But, they could do like Google and at least acknowledge it. I am hoping that they will still do that at some point today though because in response to a tweet, Dick Costolo said, "watch this space." Not sure what he means, but hopefully it means Twitter will acknowledge it.
