Extraordinary! The Blogosphere (UK division) seems to be singing with one voice - we do not approve of the Learning and Skills Council's Texting for beginners.
I don't particularly approve of Text messaging. It's a way of receiving football scores when out of reach of WAP ie on holiday. It's a cheap way of notifying sibling that one has arrived safely in abroad place. It has very limited other uses.
The only person I communicate with who has a mobile and no email is my partner: I would far rather hear his voice and conduct a conversation. He's a fifty something who doesn't like texts. Not especially because he's technophobic, but because he has to find his reading glasses to read the text. But he got one of his sons to teach him how to use it.
A colleague was saying today that a few weeks back she was in the Quiet Coach on a train. She had her phone set to silent (but vibrate). Her key pad was set to silent. The bloke opposite her told her off for sending a text, because it was the quiet coach. She pointed out that she was sending a text, silently. He still insisted she shouldn't be in the quiet coach. She pointed out that him being dense was far noisier than her sending a silent text.
