Someone on the Internet has pissed you off (I know, I know, this is an outlandish situation I’m suggesting, but bear with me). Maybe they’ve disagreed with something you firmly believe in. Maybe last night in Dragon Soul they wouldn’t get out of the fire no matter how many chances they got and kept wiping the raid. Maybe they’ve just been an absolute jerk.
Despite common practice, the appropriate course of action is not to go on Twitter and snidely make vague, undirected comments about the situation. This doesn’t fool anyone. Anyone who has been privy to the situation will know exactly what you’re talking about. The person you’re making the snide comments about will know exactly what you’re talking about. I suppose that’s the point. However, acting this way is passive aggressive and tacky. At best it accomplishes nothing. Likely, it makes everyone involved more angry and draws more people into a situation they don’t really need to be involved in.
Try taking the high road. Directly tell the person in question that you’re upset with them and why. If you feel like being super mature about it, you could even do it in private rather than on Twitter. The situation has much better chance of being resolved this way.
Communication tends to work better when you say what you mean, to the person you want to hear it.
