From today's New York Times. When the world is so broken and the best defense is a little silly sarcasm - a symbol:
"This is what we really need. For those who want to make sure their sarcasm is recognized for what it is, Sarcasm Inc., a Michigan company, has developed the “SarcMark” to identify sarcastic comments in e-mail and text messages.
"Never again be misunderstood! Never again waste a good sarcastic line on someone who doesn’t get it!” the company said on its website. It offered such examples as “I love my job” and “Because that was so much fun the last time we did it.”
Software available at Sarcasm Inc for $1.99.
