There's a good, though not well-known author Espen J. Aarseth. he analyses non-ergodic literature within the scope of computer technology, and how the latter enables the creation of texts that are not linear. An easy example would be an old-school RPG game where you can replay the game and choose different paths, which builds up to a different narrative. There's no one story and you can't define an author, because the ending depends upon the user's choices, so the "reader" participates in the "writing" process. Here's his one article that can be found online
