I've been writing reviews on this site for over a decade. Once every few years someone will actually send me a PM in response to one of my reviews, but there's a striking lack of interactivity. Not even so much as a feature to Like someone's review to show appreciation. I don't find it at all necessary for me in particular, but I think it might be healthy for the system as a whole if there were some sort of feedback mechanism to make reviews not just feel like we're shouting into an empty void. It really does feel like I'm doing this only for myself. And for my use, that's perfectly fine. But it can feel like a pretty lonely experience if your goals aren't so selfish.
