Hmm, I think point 1. applies to me as well (except for the fact that I generally do get my stuff betaed).

I'm also one of those people who would probably be discouraged from writing if I received a lot of 2. a) feedback. A lot of positive feedback could lead to writer's block because I would fear that the next story won't be as good even though the readers expect me to deliver something that meets the quality of the previous story.
