I'm reading an article about diary writing in the nineteenth century. It says:
"While a mountain of minutiae could be expected of most amateurs, on the contrary, keeping a diary helped novelist Virginia Woolf (1882– 1941) cut loose. Her hand moved over the page faster than her mind could censor it, sweeping up 'several stray matters which I should exclude if I hesitated'."
I'm confused about the first sentence. Does "a mountain of minutiae could be expected of most amateurs" mean that most amateurs wrote a lot of details? If so, it doesn't seem to be contrary to what Woolf did. If not, what does it mean?
