Mmm, what a great idea.
*Sarcasm*. </sarcasm>. #Not! Since the dawn of the postmodern age, ironical writers have struggled to imbue the printed word with the nuances of sarcasm. Solutions involve signposting suffixes like “Joke!”, so as to spell out any intended irony to those readers too thick to work it out by themselves. (Joke!)
The “SarkMark” was invented last year – a piece of punctuation that solved this massive problem once and for all. 
In fact, it was such a great idea (not!) that another typographer has come up with perhaps the best solution yet: the “Sarcastic Font”, a typeface that renders sarcastic comments in reverse italic script.
Great article, Guardian.
