I think, GPT store can attract new customers if they share at least %70 og that $20 with creators, so the creators will also be intrigued to create valuable gpts and the other unusefull craps will disappear. Surly the interface of gpt should have a description, landing and customer rating page with images and user guides.
Another way is to dismiss GPT Store and create your valuable custom GPTs on a bot framework to monetazi them.
What do you think?
