Of course it's not the same as speech, but written language can quite cheerfully play games when it wants to, to mimic speech and persuade the reader to relax into a conversational register. Shadows of our oral traditions are everywhere in our written ones. Get me drunk and ask me about the folk voice in literary fairy tale sometime.

I obviously didn't express my thought clearly - I find it interesting that you consciously make the choice to avoid any of the folk echoes in writing, in favour of a deliberately more formal tone. Other bloggers are determinedly informal. I seem to range quite happily up and down the tonal register as the mood strikes me. We are an infinitely various race.
