It wouldn't necessarily have to be a space where you can write a full review, there's not even a thumbs up/down or 5 star rating system either. There's no audience score of any kind on the app.
It's fine if you or other people like the way it is, and I'm not saying I'm super set on some kind of rating system. This conversation isn't about that, it's about how democratizing the platform is, and having an algorithm that was created by a corporation to improve their ability to generate profits curating your content consumption is not that.
Again, I get that outside sites exist where you can give your opinion on stuff, but that's beyond the scope of this discussion I think.
