It’s UX behavior… adding a comment to a topic might feel “participating” in a comment back and forth kinda mentality… I think the experience of “Adding a Review” with stars is a behavior of someone’s opinion without the expectation of “having” a conversation… and it helps to rate a brand, or a product or a service?
Just didn’t know if this was built yet or if there was a solution for this.
