I think it's hard for many to stay positive because it's so easy to be an anonymous tough guy on the web. Most wouldn't be so troll-happy in person. I think sarcastic gifs walk a fine line....sometimes it's funny, but often it's rude. I understand, for example, if someone makes a new thread asking something that's been answered a hundred times before without bothering to search....it's obnoxious. However, one can simply ignore and let the thread die instead of being a prick. The rudeness and meanness in world/local chat is a real turn off sometimes. If anything, I begin to pity the people who are always on, always starting trouble.
