Sarcasm Is Really Helpful.
Sometimes, when dealing with a particularly difficult editor or situation, you may be tempted to resort to sarcasm. That's a really great idea. Sarcasm works really well in online media, because it's so easy to pick up on without all of those pesky extratextual cues. It's hard to see how the employment of sarcasm could possibly be counterproductive.
Sarcasm is especially useful in controversial debates, where a sarcastic comment often has the effect of calming the situation.
