Personally I am not interested in one-branch stories. If I want to read those, I can go anywhere else, because it's just a normal story, in the end. I come here to CHYOA for the branches, the stories that feel, like it says on the cover "to choose your own adventure".
That being said, I wholeheartedly agree with the general idea that people should write what they like. There are more than enough stories her for everyone and their personal preferences.
