The articles are good, but I don't think the findings are substantially more unique than what probably many other people in tech are experiencing.
I don't think there is some big conspiracy behind it, but I wonder if it might be the result of some algorithmic feedback loop: The system knows those sources as valuable, so posts reach the frontpage often, so people upvote them often, so the system registers them as even more valuable, etc...
That or there is some bit of HN lore that I don't know. In which case I would be interested in learning :)
It's not that "the system" knows them as valuable, it's that people have gotten to know them over time and trust them. These are people, for me, whose articles I'll always make time for. I suspect a lot of HNers feel similar, so that's a lot of upvotes, so that's a lot of frontpage hits.
to be clear you dont owe us any of this, i'm just reporting my own confusion after going on your site and not knowing what "Archmage of Infrastructure" is (i only realized that your resume is public while typing this... oops)
