Yep, let's suppose an average HN user reads 30-100 articles a month on independent websites (personal domains) posted on HN. Out of 100, he probably subscribes to 0-2 at best (via RSS/e-mail). Now, imagine how many times you need to appear on HN to get your own audience. There is too much friction for a user to subscribe.

Substack is similar to a social platform. People open it to read new articles in a similar way to HN, and they can subscribe to anyone by pressing a single button. There is a recommendation feed as well.

Since Google search for tech content is dead, getting views on independent blogs is extremely hard.
