But reviews about missing feature, or reviews in general... that might not give you a good idea of why people are using it, if they don't leave a review at all
I have never written a review of anything in twenty years, I think. Consider that reviews are inherently biased towards people who are accustomed to speaking up, either because they like reviewing things (not many people) or because they’re upset and have a problem (many people). It becomes evident in practice that reviews generally aren’t productive to consider.
