From The Guardian:
People think that the written language seen on mobile phone screens is new and alien, but all the popular beliefs about texting are wrong. Its graphic distinctiveness is not a new phenomenon, nor is its use restricted to the young. There is increasing evidence that it helps rather than hinders literacy. And only a very tiny part of it uses a distinctive orthography. A trillion text messages might seem a lot, but when we set these alongside the multi-trillion instances of standard orthography in everyday life, they appear as no more than a few ripples on the surface of the sea of language. Texting has added a new dimension to language use, but its long-term impact is negligible. It is not a disaster.
