I really wouldn't call a lot of what's online "literature" since that word, to me, refers to a sub-genre of writing that belongs to the heavy-hitters, the canonical writers, Shakespeare, Dante, Milton, Dostoevsky, Kafka, and even Toni Morrison, George Saunders, Thomas Bernhard, Sebald, Borges, DFW, e.g.
