That would be cross browser support for MathML, or other tools to get math expressions typeset on the web. Those discussions only pop up like once every six months though. 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.
