I loved Joshua Porter's response:
“This is the Social Web. This is the point where the distinction between what’s going on offline and what’s going on online isn’t important anymore. Posting an anonymous comment is the same as yelling at someone across the street. The only difference is that its recorded for others to see.
And you know what? That might be a good thing. The silver lining is that this behavior is public, and the community is pushing back on itself. The right things are being said. “This is unacceptable.” “This is wrong.” “This is bullshit.” We won’t stand for this.”
