Computer-mediated communication (CMC) provides young users opportunities for social affinity and control over when and with whom they interact, but its long-term influence on language remains largely in the hands of parents and teachers, their traditional linguistic role models. Are email, instant messaging (IM), and text messaging on cell phones degrading the language? This question surfaces in debates among language professionals and, perhaps more important, among parents and their teenage offspring.
If some traditionalists are correct, we must take swift action now, before these children are reduced to marginal literacy. But if those celebrating linguistic innovation are correct, adults should get out of the way of normal language change. Families and educational purists have an obvious stake in the outcome of this controversy, but so, too, do the makers and marketers of computer-based software and devices—from IM platforms to predictive text programs for cell phones.
The problem with viewing CMC as linguistically either good or bad is twofold. On the one hand, such a dichotomous perspective ignores the variation in online communication, reflecting age, gender, education level, cultural background, personality, and years of experience with the CMC platform (listservs, for example, do not function like IM) or the purpose of the communiqué (a well-crafted email message applying for a job vs a hasty blitzmail note arranging to meet at the library at 10). On the other hand, many evils attributed to CMC, especially as practiced by teens, can be traced back to ARPANET days. (...)
However, the linguistic novelties cropping up in CMC are as pronounced in Stockholm and Seoul as they are in San Francisco. If we look at the history of written English over the past 1,200 years (roughly from the time of Beowulf ), we find shifting patterns in the roles speech and writing play in society. Up through the Middle Ages and the Renaissance, writing was essentially a handmaiden to speech and was generally rather formal. Preachers read the Bible aloud; written speeches were memorized and delivered orally; plays were intended to be performed, not published. Not surprisingly, orthographic conventions were not strict; even Shakespeare spelled his own name at least six different ways.
Gradually, with the spread of literacy and the rise of print culture, writing became a distinct genre. Spelling began to matter, and even those with a grammar-school education knew the difference between formal and informal writing style.
