The neat thing about HN is that I can nearly always find at least one thing on the front page that's useful to me, especially if I read the discussion.

Just looking through now, Canine is interesting because it's similar to Dokku, which I already use. I might consider using Canine in a similar role in the future if I want k8s with buildpacks.

The Dull Men's Club groups aren't like that. The needle to hay ratio is far worse. It's all "huh, cool" coincidences and mysterious objects, but nobody really intends to show the world anything useful.
