Written sarcasm

Sarcastic speech is an art-form largely based on body language and tone, neither of which are effectively communicated in written text. Far too often a carefully crafted biting remark is completely lost on the reader. I recently heard someone suggest that we need a font to denote sarcasm. This idea is, of course, nothing new and certainly not my own, but I offer a different take on it. Therefore in my writing I will be instituting a new standard: squiggly brackets shall henceforth border a sarcastic remark. Besides, when was the last time you used brackets for any other purpose? Examples would be:

• I saw the report you wrote yesterday. {Good job.}
• Your dog puked on my sweater. {Thanks for that.}
• {I think Transformers 2 was a serious work of art.}
