Wanted: Tech Person Fluent in English, Sarcasm

English has long been the lingua franca of the Internet and tech industry, and many firms operating in international markets are investing in English lessons for their far-flung executives. Teaching English isn't necessarily as hard as teaching sarcasm. Computer Sciences Corp. recently expanded its English literacy program for its non-U.S. executives to include lessons in regional colloquialisms, sarcasm and cultural communication norms. CSC and other firms have found that speaking the same language isn't enough; execs must understand the nuances of the language and the expressions particular to it. Misinterpretation could put a company's global business at risk. N'est-ce pas?
