Can confirm the depth and longevity of mailing lists compared to classic forums and HN/Reddit with sometimes week-long threads if not necessarily with daily or more frequent cadence which also works wonders for quality. Think open-ended discussions and responses without time pressure but with good quotes and references rather than "quick wins", memes, and barely hidden intents of manipulation which is also a thing on HN. Also, the option of PMing. Mailing lists should be used more again, they've become somewhat out of fashion for no good reason.
