(Just to be clear, I'm only interested in this from a perspective of understanding HN, which is a de facto barometer of "which way the wind is blowing" in tech and has a looooot of influence in our industry. If HN moderators are steering that influence far more than is previously known, that's huge.)
That really does not follow, for a couple of reasons.
One:
As Gruber freely admits, maybe his writing just sucks now or HN's interests have shifted away from DF.
This is entirely plausible but if this is the case we'd expect a more gradual decrease of DF engagement on HN and not an abrupt and near-total cessation.
Two:
I do not think that the popularity of "organic" traffic to a website correlates strongly with the engagement on HN. Glance at the HN home page, and what do you see? The overwhelming majority of links are to domains that get an order of magnitude less traffic than DF. The current top two:
- Getting hit by lightning is good for some tropical trees (caryinstitute.org) (98 points)
- Architecture Patterns with Python (cosmicpython.com) (369 points)
Here's Similarweb's estimates for traffic to the following domains from 12/24 through 2/25.
- Daringfireball.net: 1M
- CosmicPython.com: 72K
- Caryinstitute.org: 92K
They're just estimates, but have you ever heard of the other two? The relative magnitudes certainly feel more or less reasonable here.
