It was only a matter of time before Moretti's writing style started grating on me.
I'm going to be quite honest when I say that I'm not sure what Moretti's reasons were for writing this chapter. It seems to be some rather basic level stuff: with maps, we can abstract information from literature and visualize it, placing characters, places, etc. in relation to each other in the process. Also, maps are different than graphs, and the shapes of genres change with time. Maybe I'm missing something, but I just really couldn't see what type of new information Moretti was trying to present here.
I am really looking forward to mapping out some stories from Dubliners though.
