/lit/ - Literature

So I've taken the habits of reading books on the subway for the last months or so and displaying them very high in front of my face so that everybody can see the cover clearly and engage conversation about it, also I read one book a week so this should maximize the odds that I meet people with common taste, and yet still no literary gf. What is likely to be my mistake there ? Also do note that the subway I take only travels through p patrician districts.
