Exactly. You hit the nail on the head imo. I didn’t even think about this particular mechanic until you mentioned it.
People are so used go „reaction content“ and „reacting“ passively that this place does not grow as fast as it probably could if people were more creative. Creativity is like a muscle. If you don’t train it, it’s really weak.
So, I think it’s very much a good idea to put some easily visible „suggestion“ somewhere that this place will improve as much as you make it by posting original content ie questions and ideas.
