You don't have to do shit. If I'm gonna write a sarcastic comment, the joy is in knowing that some people will just think I'm a fucking moron. People who get it will relate. Others won't. The world will spin. I'm not writing sarcasm in a public broadcast built for mass audiences. It's a specific communication for a specific audience. If someone doesn't get it, tough shit for them...

The real useful one is /gen when ppl need to know you're NOT joking.
