I find myself learning a lot more about e.g. problems in software engineering "in the large" than I otherwise would because HN is such a nice experience overall. But I'm keen to learn more about e.g. logistics from the same kind of practical atmosphere where links are timely, knowledgeable and relevant, and commenters are intelligent and often experienced.
What do e.g. air cargo in passenger planes people congregate? Or warehouse people?
There's datatau.net for data science, but it's not very active. Has great potential but I think the mod(s) have been very quick to shadowban users for posting anything remotely commercial. So now it's just the same few people posting Medium and TowardsDataScience articles. I hope it can be revitalized or someone else makes a better HN clone.
For blackhat seo the site below is interesting to poke through every once in a while. I would highly recommend never using any tactic posted, but interesting to see people trying to game google's algorithms. A good chunk of it is mildly technical but understandable by most.
