As a poet, I was drawn to the unique style. As an avid reader, I fell in love with the brightly drawn characters. As a book group discussion leader, I reveled in the themes and layers of this highly praised novel. Folks, I read it in one sitting, completely absorbed by the setting.

Punctuation has evolved over time as a means of transferring a story from the writer to the reader without the reader having to attend to the medium.
If I have to work out where dialogue starts and ends I'm spending more time concentrating on the typed words than their contents. More time on the author's idiosyncrasies than the story.
I'm not interested in the former, I want to enjoy the latter.
Punctuate it and I might read it.
