While some of the comments here on FR do fall under the category of irony, many more fall under the banner of sarcasm, which is fine, but many posts are just mean. People will post something just to say something mean or sarcastic, without having any real content. I appreciate humor (especially dry humor). Additionally, I happen to fall into the camp of thought that believes sarcasm is the lowest form of wit (I believe Oscar Wilde said that) and it is so over-used in our society, frankly, it's become banal.
