I’m actually way more of a lurker here. There are e.g. once a month a submission about Bayesian Analysis (and a guaranteed once a year submission about Kalman Filters) which I religiously read but hardly ever contribute to (unless a frequentist is advocating for IQ tests or other psychometric devises; then I for sure contribute; but that can lead to flame-wars easily). Every so often there is a back end engineer with an “opinion” on the front end stack which I sometimes answer for, however that often be a flame-y subject, for some reason I’m less tempted to be sucked into flamewars when the subject is actually aligned with my expertise.
