Swiss linguist Ferdinand de Saussure was a clever bloke. He distinguished between 2 languages: langue, the language, and parole, the spoken language. We speak one, and we read and write the other. They can be quite different.
So it seems a bit odd to me that we write to be read, rather than to be heard, especially in the stripped down, dumbed down, sound-bite-driven world that we inhabit these days. The blog seems to me to be a classic example of this. You can certainly get quicker through those posts that are written closer to the language of conversation.
Re-read the sentences from this post. Could you see yourself saying them, exactly as written? Some of them maybe, others not? Odd, isn’t it? Perish the thought you do a spell check and Word tells you your sentence is not a sentence, but a fragment. Shocking. 🙂
