Sarcasm moves forwards, or is it backwards?

Typographer, Glenn Mcanally, has come up with perhaps the best solution to conveying sarcasm yet: the โ€œSarcastic Fontโ€, a typeface that renders sarcastic comments in reverse italic script.

The manifesto says:
For too long e-mails, instant messages, web pages and documents have been unable to fully communicate the subtleties of sarcasm. Text delivered without intonation fail to represent the rare form of language where the intended meaning is the opposite of the written word.
