As someone who occasionally does write in /lit/, I'm motivated primarily by my own desire to write.
Likes/dislikes can be too easily abused by people who don't like the fetishes you, the author, are into. That can be far more damaging than whatever positive feedback can be achieved by likes. If someone wants to leave positive feedback, or criticism, they can write a simple post in the thread. A shitposter is more easily ignored if they have to actively shit out a dumb ass post, whereas actual criticism of the story is more valuable in the form of a well written post in the thread.
