Hunting of the Snark:

So I’d think twice about deciding your online persona is “righteous asshole.” If it seems like a good idea, think two more times. You are not speaking truth to power. It is not a litmus test for determining your true friends. You are not guaranteed that only the “right” people will be pissed off. And you will build an audience that rewards you for being unkind—which makes it all too easy to cross lines you shouldn’t. When you get called on it, it’s too late to rip off your asshole mask and protest that’s not who you really are.
